The planetary reducer is installed in the head and tail of the conveyor to adjust the working speed of the sprocket shaft set and the carrying capacity of the scraper chain, so as to suit the working needs of different design power and rotating speed of the scraper conveyor.
According to the different structural characteristics of the reducer, the use of different, its general classification is as follows:
1. According to the series of transmission, it is divided into single-stage reducer and multi-stage reducer
2. According to the type of transmission, it is divided into fixed-axis reducer and planetary reducer
3. According to the layout requirements of scraper conveyor, it can be divided into parallel layout type and vertical type
Scraper reducer is mainly used for planetary reducer. Compared with fixed-shaft gear transmission, planetary gear transmission has more compact structure, more stable transmission, larger transmission ratio of the same series, and better performance in bearing capacity. But because this kind of decelerator usually has three or four planetary wheels in the planetary frame design, its structure is more complex, the parts processing precision request is higher.

Compared with the casting process, the forging process of 17GL7-1 scraper conveyer can make the hardness, strength and service life of the scraper more in line with the service requirements. But the forging process of 17GL7-1 scraper is difficult to be controlled in the actual production process. The following coal manufacturers double zhi machine will give you the introduction of 17GL7-1 scraper forging process of the three points.
1. Heat the scraping slab
The main purpose of heating 17GL7-1 scraper blank is to increase its hardness, toughness and service life. When 17GL7-1 scraping slab is heated and tempered, the oxide layer on the surface of the slab is constantly knocked out to ensure the hardness and toughness of the product, and meanwhile, the smoothness and flatness of the surface of 17GL7-1 scraping slab is also ensured. In the process of shaping the billet, the temperature should be lowered to about 1100 degrees Celsius to achieve a good shaping effect and increase the plasticity of the scraper.
2. Control of quenching temperature
After being heated and tempered, the 17GL7-1 scraper needs to be put into water to be quenched, so that the hardness and strength of the 17GL7-1 scraper are strong. Quenching temperature control is the key and difficult point in the forging process of scraper. Good temperature control can ensure the quality of the scraper and the surface flatness. If the temperature difference is too big, it will lead to the surface of the scraper crack. In quenching, the need to choose the appropriate quenching temperature according to different scraper material. When quenching, field tests should be carried out to control the hardness value. After the scraping plate quenching, but also for the scraping plate residual temperature treatment.
3. Impact energy of a forging hammer
China's scraper conveyor production started late, the initial use of the type of die forging hammer is relatively small, the hardness and quality of the die forging hammer is greatly limited, the impact energy of the die forging hammer is far unable to reach the production of the strike energy required by the scraper. The hydraulic force is then used to increase the impact energy of the hammer. The impact quality of the die forging hammer meets the requirements of the scraper manufacturing, the production of 17GL7-1 scraper quality, hardness can be qualified.
The above is the key and difficult points of 17GL7-1 scraper forging process. Henan Shuangzhi Machinery Equipment Co., Ltd. based on the coal machine industry for many years, mature technology, diversified equipment, the production of coal machine parts forging strength, high hardness, strong toughness, well received by customers, if you have coal machine parts procurement needs, you are welcome to inquire, to visit the factory.
The dumbbell pin plays an important role in the normal operation of the scraper conveyer as the connecting member between two adjacent chutes. Today the coal machine parts manufacturer Henan shuanzhi will introduce the dumbbell pin of scraper conveyer for you.
Scraper conveyor dumbbell pin shape is like "fitness dumbbell", the middle is thinner, thicker at both ends. The dumbbell pin jams the ends of the two adjacent middle slots by the thicker ends at each end and connects the two adjacent middle slots by the thin middle rod. In addition to the common dumbbell pins described above, there are two types of special shaped dumbbell pins - I-type dumbbell pins and day-type rings.
The stress condition of dumbbell pin is more complicated. In the process of hydraulic support moving the middle trough, the dumbbell pin will be pulled by the adjacent middle trough and subjected to shear stress because the adjacent chute is not synchronized.
The dumbbell pin of scraper conveyor is a vulnerable part, and the common fault is fracture. The first crack occurred in the neck of the dumbbell pin, mainly because the neck of the dumbbell pin is a region where stress concentration is relatively large. Under long-term working conditions, the dumbbell pin's neck crack growth area diffused to a certain extent, resulting in fatigue fracture, resulting in the fracture of the whole dumbbell pin.
Once the dumbbell pin is broken, it will cause the middle slot dislocation or off, the scraper chain is affected by it, easy to break the chain, the chain clip, from the chute off the phenomenon, affecting the scraper conveyor working surface production safety and normal production.
Above is the dumbbell pin on the scraper conveyer, do you know? The dumbbell pin of the scraper conveyer produced by Henan Shuangzhi is forged from the selected material of 40Cr, and the quality is comparable to that of the original products after multiple processes such as tempering and quenching. More scraper parts, transfer machine parts, hydraulic bracket parts related product models, product information, you are welcome to consult.
The hydraulic chain tensioner has the following advantages:
(1) The braking mode is reasonable and reliable. In the large scraper conveyor, the excessive torque can not be braking through the brake disc, and the hydraulic motor tight chain system internal braking function braking, the way is more reasonable, more reliable.
(2) Low fastening speed is conducive to control. The hydraulic motor tightens the chain, the motor speed is 100 RPM, after the reducer, the drive sprocket speed is lower, the chain speed is lower, more conducive to control.
(3) Simple operation, more conducive to control. Compared with the brake disc chain tightening device, the scraper conveyor hydraulic motor chain tightening system only needs to pull the operation handle or press the operation button, and the hydraulic system can complete the chain tightening.
(4) High safety factor. Hydraulic motor chain fastener has the advantage of hydraulic system, compared with the brake disc chain fastener of mechanical brake, overload unloading and transmission torque is more stable, high safety.
Scraper conveyer hydraulic motor tight chain system progress day by day, together with the coal mine fully mechanized working face automation degree more and more high, will become the future coal machine configuration mainstream. Henan Shuanzhi production of various types of hydraulic chain, brake disc chain, about more scraper accessories, you are welcome to telephone consultation.

Sprocket components and scraper chain as the important transmission configuration of scraper conveyor, if there is a fault, it may affect the normal operation of underground coal mining work. So how do you deal with such situations?
The sprocket components sometimes has the phenomenon of high temperature in the operation process, the cause may be the insufficient lubricating oil, or the damage of bearing and sprocket may cause the aggravation of friction, which makes the temperature rise. Then the solution is to oil the sprocket assembly, so that the amount of oil to the specified requirements, or replace the worn bearing, sprocket body to make a new replacement.
The scraper chain has the condition of jumping teeth at the sprocket assembly, which is caused by many factors, such as too loose scraper chain, twisted chain segment, unequal length or elongation of double-strand chain or different number of rings, as well as the influence of excessive scraper deformation. The correct treatment method is to adjust it: re-tensioning the scraper chain, re-install the twisted chain segment correctly, check the scraper chain length and elongation if unqualified, it should be adjusted and replaced, and must use the odd ring chain, and is to replace the seriously deformed scraper.

The middle trough of the scraper conveyor is one of the key parts of the scraper conveyor, and it is the fuselage of the scraper conveyor. Only the volume and quality of the scraper conveyor occupies about 70% of the scraper conveyor machine. Scraper parts manufacturer Henan shuangzhi below for you to introduce the scraper middle trough.
As an important spare part of the scraper conveyor, the middle trough of the scraper is not only the bearing mechanism of the material and the scraper chain, but also the important fulcrum of the hydraulic support. Each scraper is generally equipped with more than 100 middle slots, the length of the middle slot is mainly 1.5m and 1.75m two types. Therefore, the service life of the scraper and the transport volume are largely determined by the service life of the middle slot.
The middle slot is mainly made of the groove side and the middle plate. The material is mainly 16Mn and ZG30SiMn2 of high manganese steel.
According to the different manufacturing technology of the middle slot, the middle slot can be divided into welding middle slot, casting middle slot and integral casting middle slot.
According to the different structure of the central trough, the central trough can be divided into the open bottom middle trough and the back end middle trough.
The middle groove can be divided into the middle groove of the single and the middle groove of the double.
The central trough of the scraper is in direct contact with the material, coal gangue and scraper chain, which is easy to be affected by it and will cause scraping and wear for a long time. The middle plate, bottom plate and groove top of the middle slot are the most prone to wear. The main wear forms are abrasive wear, fatigue wear, adhesive wear and corrosion wear.
Henan Shuangzhi, as a highly praised scraper conveyor accessories manufacturer in the industry, improves the abrasion resistance of the central slot of the scraper by adopting wear-resistant materials and optimizing the surface strengthening technology of the central slot.

The E bolt is suitable for the scraper conveyer of the fully mechanized mining, and it is the common fittings of the equipment of the fully mechanized mining. The E bolt is used to fix the scraper on the chain (forming the chain of the scraper), and the chain of the scraper bypasses the sprocket for the stepless closed cycle operation to complete the coal transportation.
The common material of Type E bolt is 40CR, which can also be determined according to customer's requirement. Common Types of E-bolts: 3TY-48, 3TY-02, 3TY-06, 113S011208-2, 54SA14-3, 121S03/01-4, 15GL-2, 2S06-2B, 4GL-1, 1GL3-2, 15GL01-2, 134S011609-2, 90S012107-2, etc. Specifications of Screw thread of E-bolts: Using M24 studs or M30 studs, some manufacturers will produce some custom bolts, using different studs, there are M22, M26 and other non-standard bolts. The studs of the same standard are slightly different, such as type E bolts of 90S, which are divided into M24*2 filaments and M24*3 coarse filaments.
Type E bolts of scraper accessories belong to vulnerable parts, so most commonly used bolts are in stock, from material to processing technology to meet customer requirements. Need scraper, bolt, dumbbell pin and other easy to wear parts, welcome to inquire.
The gear track of the scraper is installed on the gear track seat of the middle slot, which is the track supported and guided by the shearer. It is an important support point for the stability of normal coal mining for the shearer to realize the haulage of the shearer relying on the tooth and rail pin tooth of the scraper. Therefore, scraper conveyor parts manufacturers remind you to use a more durable scraper conveyor gear track.
At present, the teeth and rails of the plate scraper in the market mostly adopt the structural forms such as integral die forging, integral casting, split welding and forging welding. Fission welding type rack and forge welding type rack is a compound structure, by putting the two track plate and pin gear processing compound into an organic whole, due to welding and machining accuracy cannot be guaranteed, so prone to open the phenomenon such as welding, fracture, wear, these two kinds of structure of the rack can't meet the need of the high-power coal winning machine supporting the fully mechanized coal face. Although the whole cast gear track avoids the problem of gear track cracking to some extent, the casting strength obviously fails to meet the use requirements, which affects the coal mining efficiency.
The integral die forging gear track is strengthened by heat treatment of alloy structural steel. It adopts die forging technology and completes the manufacturing process by a series of procedures such as forging, forming, trimming and punching. Therefore, the overall strength of the tooth and rail of the scraper is higher than the above three technologies, the pin tooth position and tooth shape processing accuracy is more guaranteed, can make the shearer and the tooth and rail better mesh, the impact force in the use process is also smaller, for the large power shearer, conveyor supporting use to provide a guarantee.
The integral die forged gear rail can meet the required performance requirements and is more durable. After reading, you choose and buy which scraper gear rail heart roughly spectrum! Henan Shuangzhi produces various types of gear rail forgings, scraper forgings, sprocket components, etc. If you want to know more, you are welcome to contact us in time.

The 52ZJE010102 sprocket assembly is the key transmission part of the scraper conveyor, and its running performance has become the condition to improve the performance of the scraper conveyor.
52ZJE010102 sprocket assembly is centralized with oil tank storage thin oil lubrication, lubricating oil is N320 extreme pressure gear oil. Lubricating oil enters the 52ZJE010102 sprocket assembly through the hose of the oil tank, making it more convenient for refueling and extending the service life of the shaft assembly. Among them, sprocket is forged by alloy steel. In order to enhance its strength and extend its service life, it adopts tempering and surface hardening treatment. Generally after being put into use, it is recommended to replace the sprocket installation direction and change its bearing surface to extend its service life when the bearing side tooth surface is badly worn.
Check whether the 52ZJE010102 sprocket assembly operates normally, whether there is oil leakage, oil temperature shall not exceed 90, whether the auxiliary fuel level is insufficient, etc. Let the scraper conveyer operate normally, Henan Shuanzhi welcomes you to inspect.
The connecting head of hydraulic support is also quite common in the daily procurement of hydraulic support parts. Its main function is to connect scraper conveyor and hydraulic support organically to realize the role of force transmission between them. When working, the connecting head has to move the bracket and push the conveyor to carry out the operation, completing the organic operation of these two links. When the hydraulic support connector works under the alternating stress of tension, compression and torsion, if the working environment in the mine is poor and the air is humid, there may be many unexpected factors, leading to the deterioration of the stress of the connector. Once the connection is damaged, the scraper conveyor and hydraulic support may not work normally, which may be shut down and stop production, causing huge losses. Therefore, it is necessary to check the first vulnerable parts of the hydraulic support connection from time to time, so as to avoid production problems.
The hydraulic support connection head is relatively simple in structure, which mainly needs to pay attention to its quality, so as to avoid the stop-production caused by penny wise and pound foolish. Henan Shuanzhi production of various types of hydraulic support connecting head, the quality of reliable.
Hydraulic support is the support equipment above the working face in coal mine production. It has a lot of fittings, such as hydraulic support connecting head, cylinder jack, top beam, bottom beam, etc. What is the use of hydraulic support connectors? So let's talk a little bit about that today.
The connecting head of hydraulic support is also quite common in the daily procurement of hydraulic support parts. Its main function is to connect scraper conveyor and hydraulic support organically to realize the role of force transmission between them. When working, the connecting head has to move the bracket and push the conveyor to carry out the operation, completing the organic operation of these two links. When the hydraulic support connector works under the alternating stress of tension, compression and torsion, if the working environment in the mine is poor and the air is humid, there may be many unexpected factors, leading to the deterioration of the stress of the connector. Once the connection is damaged, the scraper conveyor and hydraulic support may not work normally, which may be shut down and stop production, causing huge losses. Therefore, it is necessary to check the first vulnerable parts of the hydraulic support connection from time to time, so as to avoid production problems.
Casting steel structure is mostly used in daily connection, which has the advantages of reliable connection and convenient manufacture. But cast steel also has a big problem, that is, in the process of smelting and crystallization, the inherent unevenness. Many studies have shown that such inhomogeneity can effectively improve the bending strength and hardness of the material under certain conditions, but deteriorate the toughness and plasticity of the casting, and even reduce the tensile strength of the casting, which is bound to result in the failure of the casting to give full play to the potential properties of the metal material in use. In many mines, the use of this type of joint head, after a large impact, hard roof under the load conditions, will lead to a serious fracture phenomenon of the joint head, will affect the normal production. Therefore, according to customer demand, there are die forging and free forging to enhance the toughness of the joint.

With the improvement of the production capacity of coal mine in China, the model of scraper conveyor is getting bigger and bigger, and higher requirements are put forward for the spare parts of scraper. The traditional brake disc type tight chain device has been unable to meet the requirements of production, scraper conveyor hydraulic motor tight chain system has become the choice of more large scraper conveyor.
The hydraulic motor tight chain system has the following advantages:
(1) The braking mode is reasonable and reliable. In the large scraper conveyor, the excessive torque can not be braking through the brake disc, and the hydraulic motor tight chain system internal braking function braking, the way is more reasonable, more reliable.
(2) Low fastening speed is conducive to control. The hydraulic motor tightens the chain, the motor speed is 100 RPM, after the reducer, the drive sprocket speed is lower, the chain speed is lower, more conducive to control.
(3) Simple operation, more conducive to control. Compared with the brake disc chain tightening device, the scraper conveyor hydraulic motor chain tightening system only needs to pull the operation handle or press the operation button, and the hydraulic system can complete the chain tightening.
(4) High safety factor. Hydraulic motor chain fastener has the advantage of hydraulic system, compared with the brake disc chain fastener of mechanical brake, overload unloading and transmission torque is more stable, high safety.
Scraper conveyer hydraulic motor tight chain system progress day by day, together with the coal mine fully mechanized working face automation degree more and more high, will become the future coal machine configuration mainstream. Henan Shuanzhi production of various types of hydraulic chain, brake disc chain, about more scraper accessories, you are welcome to telephone consultation.
Hydraulic prop is generally composed of piston, piston rod, cylinder block three parts. Because the support work, the column bearing capacity is large, and the drop column force is small, so the piston rod diameter is larger, often use hollow structure, in order to ensure sufficient stiffness of the piston is generally y sealing ring, copper ring guide, cylinder bottom welding. The cylinder block and the cylinder head are connected by steel wire, thread or clasp. In order to prevent the external coal seam and other stolen goods into the cylinder block, the guide sleeve should be equipped with a dustproof ring. For the single telescopic column, in order to expand the support height of the hydraulic support, can use mechanical extension rod, the head structure of the column is spherical, and the connection between the top beam or the base with pin shaft or block fixed, in order to make the column in the work by a certain adaptability.
The liquid supply method of hydraulic prop consists of two ways: internal liquid supply and external liquid supply. In addition to the double telescopic column with internal liquid supply mode, the single telescopic prop is mostly external liquid supply mode, which is simple in structure, convenient in processing and maintenance.
The main function of the connecting head of the hydraulic support is to connect the scraper conveyor and the hydraulic support organically to realize the effect of force transmission between them.
When working, the connecting head has to move the bracket and push the conveyor to carry out the operation, and the organic operation of these two links should be completed. Therefore, in addition to the alternating stress of tension, compression and torsion, and the poor working environment in the mine, and the heavy humidity in the air, there may be many unexpected factors, leading to the deterioration of the stress of the joint head. Once the connection is damaged, the scraper conveyor and hydraulic support may not work normally, and may be shut down and stop production, causing huge losses. Therefore, the hydraulic support connection head also plays an important role in coal mine production.

Fixed protection, such as wooden brackets, shall be applied in the delivery and transportation of y303-30 hydraulic support columns. In case of large quantities, such as hydraulic jacks, which are delivered in batches, shall be bundled firmly to avoid falling off, extrusion, rolling collision and other damages. If it is in winter, the product should be injected with antifreeze according to the low temperature of the applicable area and the transportation distance. In other seasons, the emulsion in the column of Y303-30 hydraulic support should be emptied. However, the transportation and storage process of the column after the drainage should be guaranteed, and no corrosion phenomenon should occur inside.
If the hydraulic support column of Y303-30 has been stored for more than three months, the emulsion in the hydraulic support column should be checked for deterioration. If so, the emulsion should be replaced. When the drainage method is adopted, the rust should be checked. The hydraulic support column of Y303-30 should be paid attention to and ensure that the joint seat is not damaged during the use, and the transportation package should be strong and reliable. The column should be loaded and unloaded lightly in the process of transportation. Special attention should be paid to the joint seat so as not to damage the interface and affect the connection use of the hydraulic support column.
In fact, the above methods are not only for y303-30 hydraulic support column, but also for all kinds of hydraulic support jack cylinders. In transportation, storage and use, some problems can be avoided for the hydraulic support column or hydraulic support jack. Henan Shuangzhi Machinery as hydraulic support accessories manufacturers, can produce and process hydraulic support column, hydraulic support jack, bed beam, bed, bottom adjustment beam and other accessories, welcome new and old customers to consult understanding, looking forward to working with you!
The hydraulic prop is the main component to support and carry the hydraulic support, it directly affects the performance of the hydraulic support. Therefore, in addition to reasonable working resistance and reliable working characteristics, hydraulic prop must also have enough compressive and bending strength, good sealing performance, simple structure and suitable for the work of hydraulic support needs.
Hydraulic prop is generally composed of piston, piston rod, cylinder block three parts. Because the support work, the column bearing capacity is large, and the drop column force is small, so the piston rod diameter is larger, often use hollow structure, in order to ensure sufficient stiffness of the piston is generally y sealing ring, copper ring guide, cylinder bottom welding.

Hydraulic cylinder can be referred to as hydraulic cylinder, hydraulic system is the executive element. From the function point of view, the hydraulic cylinder is the pressure energy into mechanical energy conversion device. So how does a hydraulic cylinder work?
According to the structure and working characteristics, the hydraulic cylinder can be divided into single action hydraulic cylinder, double action hydraulic cylinder, combination hydraulic cylinder, swing hydraulic cylinder and telescopic hydraulic cylinder. In general, we commonly used is the use of piston rod double - acting hydraulic cylinder. We also generally understand the principle of double acting hydraulic cylinders, so today we will look at the principle of single acting hydraulic cylinders.
The so-called single action hydraulic cylinder, is that the pressure oil can only supply oil to one side of the piston chamber in the hydraulic cylinder, the oil pressure pushes the piston to move in one direction. When the motion is complete, the piston returns to its original position by its own weight or other factors. The double-acting hydraulic cylinder may supply oil to a cavity with or without a piston rod at one end. By changing the direction of the oil input, the oil pressure pushes the piston up and down or to the left and right.

The hydraulic support connector is a vulnerable part. After the casting was used, the forging process was changed because the strength could not meet the requirements. Today, I have a preliminary understanding of the processing technology of the hydraulic support connector.
At first, the free forging process was adopted, and later it was changed to gas cutting forming. Due to the limited forging tonnage, the blank margin produced by forging has a large rough edge, and the forming ability of semicircle ball is poor. Later, after improvement, it can save materials and man-hour, simple operation, high production efficiency, flexible process operation, and local forming.
As the main connecting part of hydraulic support, the connecting head is easy to wear out, so it has high requirements on material technology. On the one hand, it can improve the service life and then reduce the maintenance and replacement cost. If you need hydraulic support connector, please contact us

Shaft forgings occupy an important position in forgings and are widely used in mining machinery, petroleum machinery, chemical machinery, etc. Shaft forgings are often used as the basic parts of equipment and the core parts of mechanical equipment, which have higher quality requirements, so the forging process requirements are also more stringent.
In order to meet the performance requirements of shaft forgings, in the process of producing forgings with forging hydraulic press, it is necessary to constantly measure their diameters, and then feed the results back to the control system, which can adjust the pressing volume of the press to obtain the final size of forgings. Generally, shaft forgings are completed in the following three stages.
The first stage: forging and compaction are required for loose and porosity defects of steel to obtain forged microstructure, meet mechanical properties requirements.
The second stage: complete forging of internal porosity defects to prevent new internal cracks.
The third stage: control the generation of mixed crystal.
The forging process of shaft forgings should be as simple as possible, with less heat and no upsetting. To effectively separate the forging compaction from the final forging forming. As a forgings manufacturer, Henan Shuanzhi produces all kinds of mining machinery forgings, petroleum mechanical forgings, chemical mechanical forgings, etc.

The quality inspection of die forgings includes appearance quality inspection and internal quality inspection, including numerous inspection items respectively. The first is the chemical composition inspection, usually based on the smelting before the furnace sampling analysis as. Especially for important or suspect die forgings, some chips can be cut from the forgings and chemical composition can be tested by chemical analysis or spectral analysis.
Secondly, the size and shape of die forgings are checked. Visual inspection is a more common method to observe the surface of forgings with the naked eye whether there are folding, cracks, bruises, scars, surface burns and other defects. And the surface of die forgings hidden deep defects, often after heat treatment and cleaning for observation. And its dimension measurement inspection includes length, width and height dimensions; Parallelism and perpendicularity of the plane; The curvature of the axis; Ellipticity of inner and outer circles; Radius of fillet; The concentricity; The included Angle and the misshift, etc.
When the die forgings are required to carry out the precise size inspection, in addition to the marking inspection and the special sample can be used, the inspection instrument controlled and analyzed by the computer can be used, or the optical comparator, optical projector can be used for the relevant size inspection, to ensure the accuracy of the inspection results.
Surface flaw detection is also a part of the quality inspection of die forgings. The surface quality of membrane acid and base is determined by magnetic particle test and fluorescence test. In addition, there are ultrasonic inspection, low tissue inspection, microscopic inspection, residual stress inspection and so on, each link can not be ignored.
Hydraulic support pin shaft is usually used for the joint of two parts to form a hinge connection.Hydraulic support pin shaft according to different functions can be divided into the following types:

The crushing shaft is composed of crushing shaft, cutter tooth base, cutter tooth, flat key, bearing, seal and fastening bolt. The strong rival of coal "big block" is broken shaft group, today we are going to introduce this "strong rival"!
Trough crusher is used with the transfer machine, using the high speed rotating hammer head to impact and squeeze large raw coal, so as to achieve the required particle size. The crushing shaft assembly is the key component of the crusher, which requires high precision and high stiffness. The middle part of the spindle is equipped with hammer head, which is directly involved in impact crushing. Its performance is the key. Due to the large impact load of the hammer head, high rotation speed, the use of mining is extremely bad, so the performance of the hammer head largely determines the reliability of the crusher.
Main parts function, structure characteristic and installation and maintenance of broken shaft
1. The rotating part of the crushing shaft assembly shall not contact with any other parts in the box body.
2. The distance between any particular point of the rotation part of the crushing shaft set and the side wall of the crushing box is equal on the circumference of the crushing box.
3. The fastening bolts between the cutter body and the cutter tooth base shall not be loosened, and the cutter body shall not be cracked.
4. Manual rotation of the crushing shaft should be smooth and sound.
5. There is no bump mark in the belt groove on the pulley.
6. Prepare for complete machine test in coordination with other parts.
Common hammer head hammer head materials are: high manganese steel, low carbon alloy steel, high chromium cast iron. High manganese steel has better toughness, better technology and lower cost. But the processing hardening of high manganese steel requires higher processing technology. If the impact force is not enough and the contact stress is too small, the surface cannot be hardened. Low carbon alloy steel has high hardness and toughness. At the same working strength, the service time is twice that of high manganese steel. High chromium cast iron has poor toughness and is prone to fracture. High chromium cast iron is usually used as hammer handle on the head of high manganese steel and low carbon alloy steel to make it have hardness and toughness.
The quality of manufacturing process is to determine the service life of the hammer head. If there are shrinkage holes or cracks on the surface or inside of the hammer head, it will reduce the performance of the hammer head and even cause fracture in the operation process, affecting the working efficiency. In the manufacturing process of hammer head, forging and heat treatment process should be strictly controlled, and strict quality inspection process should be established.
Hammer heads of different structure and geometry have different performance after heat treatment and forging. Generally speaking, the thicker the hammer head, the larger the size, the less easy to penetrate. However, it is limited to change this situation through reasonable heat treatment and forging, so it is still necessary to optimize the structure and shape of the hammer without affecting the use effect.
In general, the rotor speed of the broken shaft group is high, the greater the impact force on the hammer head, it can be better impact hardening. But also can cause the hammer head service life to reduce, the crusher power consumption is too big. Therefore, a reasonable speed should be set.
If the clearance between crushing shaft rotor, grate, crushing plate and feeding roller is too small, it will lead to the blockage of coal. If the clearance is too small, the crushing effect and efficiency are too low. Hammer head crusher in the use of time, often adjust the clearance between the parts, so that it in the appropriate range.
The shape and quality of hammer head directly affect the yield and service life of the crusher. When buying a crusher hammer head, pay more attention to the above mentioned factors, choose suitable for toughness hammer head. Henan Shuangzhi Machinery Equipment Co., LTD. Produces hammer head of crusher, crushing shaft group, scraper conveyor accessories. Welcome customers to purchase.
The crushing machine series of mine scraper conveyer is mainly used in combination with the transferring machine and complete the conveying task of underground comprehensive mechanized coal mining with belt conveyer, scraper conveyer, shearer and hydraulic support.
The models of mine crusher are PCM, PEM, PLM, etc. They are respectively represented as hammer crusher, jaw crusher, wheel crusher, etc. According to different working face and production capacity of mine, different crushing capacity of crusher is required. For example, PLM3000 wheel crusher has crushing capacity of 3000T /h. PLM4000 wheel crusher with crushing capacity up to 4000T /h.
The crushing shaft group is the main component of the crushing coal and gangue. Using the broken shaft set higher rotational inertia stored at rated speed kinetic energy by installing group on the shaft of the broken blade and the broken material short contact time and impact break coal formation, again by cutter tooth and scraper chain, crusher, the speed difference between further to crush was broken coal, so as to achieve the goal of broken coal.
Shuangzhi Coal machine focuses on the production and manufacturing of spare parts of scraper machine, transferring machine spare parts and crusher spare parts for mine. It is located in Zhengzhou with developed logistics. At present, it cooperates with major mining areas all over the country.
The cutter head, also known as hammer head, is the main vulnerable part of the crushing shaft, and it is also the part that bears great impact force when crushing coal. There are castings and forgings on the market, but the castings bearing strength is small and the service life is short.
Blade was covered a layer of wear-resisting layer forging and become, blade and blade both use a special fastening bolt and nut set, blade bolts and nuts with locking washers, when wear to a certain situation or cracks have appeared, should change in time, otherwise will make the blade are installed on the part of the blade is damaged, and can no longer be tighten blade on the blade holder. The broken shaft without cutting teeth will lose its balance, and the strong vibration will shorten the service life of the broken shaft sharply.
Shuangzhi coal machine for many years focused on the scraper conveyor, transfer machine accessories, crusher accessories system repair, products sold to the major mining areas, more information please click on the official website of Shuangzhi coal machine or call to inquire the factory investigation
On the working face of fully mechanized coal mining, the trough crusher is used with the transfer machine, and the high speed rotating hammer head is used to impact and crush the large raw coal, so as to crush it into the required grain size. Hammer shaft component hammer head is the key part of the crusher, which needs to have high hardness and stiffness.
The impact on the hammer head of the hammer shaft assembly is relatively large, so the head of the hammer head should have good wear resistance and the handle should have sufficient toughness. The hammer head of the hammer shaft assembly is usually forged or cast by alloy steel, high manganese steel, cast steel and high chromium cast iron bimetallic composite. The surface of hammer head is quenched by medium frequency quenching induction equipment.
To a large extent, the damage of the crusher is due to the failure of the hammer head of the hammer shaft assembly, the poor wear resistance of the hammer head and the loosening of the hammer head will bring losses to the coal mine production. Therefore, when using the hammer head of the hammer shaft assembly, some anti-loose measures should be taken. Coal mining enterprises should also choose hammer head with good quality. Henan Shuangzhi produces various types of hammer head and hammer shaft components, complete product technology, strict quality inspection, durable and easy to use products, if you have the mining crusher accessories procurement needs, you are welcome to consult.

The hammer head of the crusher is an essential accessory for the coal mine crusher. At present, the common crusher hammer head on the market is generally divided into two kinds, forging hammer head and casting hammer head.
The hammer head of forging crusher is mainly used to heat the blank and apply pressure on the blank by forging machine to produce plastic deformation of the blank, so as to obtain the hammer head of the crusher with the given shape, size and mechanical properties. The casting loose defect caused by casting hammers can be greatly changed by forging and the structure of hammers can be optimized. Therefore, the forging hammer head performance is superior to the casting hammer head, relatively also more wear-resisting.
In order to guarantee the wear resistance of forging hammer head, it is necessary to choose the material with better wear resistance. At present, the common materials in the market include high manganese steel, high chromium cast iron, low carbon alloy steel, etc., which can be selected according to the use conditions of different mining areas.

The crushing shaft group is the main component of the crushing material, which is composed of the cutter body, cutter tooth base, crushing shaft, fastening assembly, fixing seat and other structures. After the test, it is sent to the user. What details should be paid attention to when it is put into installation operation?
1. Place the crushing box horizontally, remove the top cover, remove debris and apply anti-rust oil on the processing surface. Place the broken shaft set smoothly at the gap.
2. Use grease to empty the inner period of the rubber hose for filling bearing seat. Connect the manual dry oil station with the rubber hose for bearing seat until the labyrinth ring at both sides of the bearing seat in the crushing box spills oil.
3. Install pressure plates and dust cover plates on both sides.
4. The rise and fall of the crushing shaft set is controlled by two hydraulic jacks. Before adjusting the crushing shaft set, the tensioning screw should be adjusted to make the belt in a relaxed state. Pull out the lock pin and loosen the wedge with the jack top to adjust the crushing shaft set to the required height. Then wedge the wedge and adjust the tensioning screw so that the belt is in tensioning state, then insert the locking pin.
