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 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"!

crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated. Crushing is the process of transferring a force amplified by mechanical advantage through a material made of molecules that bond together more strongly, and resist deformation more, than those in the material being crushed do. Crushing devices hold material between two parallel or tangent solid surfaces, and apply sufficient force to bring the surfaces together to generate enough energy within the material being crushed so that its molecules separate from (fracturing), or change alignment in relation to (deformation), each other. The earliest crushers were hand-held stones, where the weight of the stone provided a boost to muscle power, used against a stone anvil. Querns and mortars are types of these crushing devices.
Brief introduction Jaw crusher is a kind of Stone crusher, and jaw crusher is also called Rock crusher. This series of Jaw crushers have many advantages which mainly used in breaking a variety of ore and the medium-size chunk of materials. The compression strength of the materials to be crushed is less than 320MPA. it can be divided into coarse crusher and fine crusher. We have all specification kinds of the products, and its feedstock size is 125mm-750mm. It is the first choice for Stone crusher plant; Primary jaw crusher is widely used in mining, metallurgy, building materials, roads, railways, water conservancy and chemical industries, etc. Features and Advantages 1) High efficiency and low operation cost; 2) Flexible capacity; Over loading protection; 3) Simple structure and easy to operate; 4) Easy replacement of wearing parts; 5) Long service life; High reliability; 6) Wide range of choices;Alternative ordinary and hydraulic types. Jaw crushers / Jaw breakers operating environment When in the process of the great broken stones broke into small stones, the first crusher is often referred to as �¢??master�¢?? crusher, the longest history and most solid crusher is jaw crusher. When feed to jaw crusher, materials from the top of the entrance into the broken room with tooth broken, the tooth broken tremendous force the material to the top of the wall, it will be broken into smaller stones. Supporting the tooth movement is an eccentric shaft. This axis runs through the fuselage frame. Eccentric movement is usually arisen by fixed at both ends of the flywheel axis. Flywheel and eccentric support bearing is often using spherical roller bearings. Bearing working environment is extremely harsh. Bearings must support enormous impact loadabrasive water and high temperature. Though the working environment is extremely harsh, the jaw crusher still can work very reliably. this is a key element to ensure the productivity. Working principle The main structure of the Jaw crusher are composed of stander, eccentric shaft, belt pulley, flywheel, movable jaw plate, wrist plate ,adjustable gap screw, offsetting spring, fixed jaw plate. The wrist plate also has the effect of guarding. This Jaw crusher�¢??s crushing style is the type of driving extrusion. The motor drives the belt and belt pulley to make the moveable jaw move through the eccentric shaft. When movable jaw is rising ,the included angle between the wrist plate and movable jaw become bigger to drive the movable plate to be close to the movable plate. At the same time the material is squeezed and rubbed, rolled to achieve multiple crushing; When movable jaw is descending, the included angle between the wrist plate and movable jaw becomes smaller. Now the crushed material is discharged from the crushing cavity, with the continuous rotation of the motor, the movable jaw crushing and discharging the material periodically to realize batch production.
According to the lamination theory, the material is broken and polished according to its own texture, forming stable stone particles, falling from the clearance of the broken wall, and the rest materials continue to be broken until reaching To the request. When the cone crusher is working, the rotation of the motor moves around a fixed direction through the belt pulley or coupling, the transmission shaft and the cone under the force of the eccentric sleeve, so that the crushing wall of the cone crusher sometimes approaches and sometimes leaves the surface of the white rolling wall installed on the adjusting sleeve, so that the ore is continuously impacted, squeezed and bent in the crushing cavity to achieve the crushing of the ore. Broken. When the non breaking foreign matters pass through the crushing chamber or the machine is overloaded for some reason, the spring safety system can realize the safety, the ore discharge opening is increased, and the foreign matters are discharged from the crushing chamber. If the foreign matter is stuck in the ore discharge opening, the cavity cleaning system can be used to make the ore discharge continue to increase, so that the foreign matter can be removed from the crushing cavity. Under the action of the spring, the discharge port automatically resets and the machine returns to normal operation.
The jaw crusher is of curved extrusion type. When working, the motor drives the belt and pulley to move the movable jaw up and down through the eccentric shaft. When the movable jaw rises, the angle between the elbow plate and the movable jaw becomes larger, so as to push the movable jaw plate to approach the fixed jaw plate. The material can be multi broken through the extrusion, rubbing and grinding between the two jaw plates. When the movable jaw goes down, the angle between the elbow plate and the movable jaw becomes smaller, and the movable jaw plate is under the action of the pull rod and spring. After leaving the fixed jaw plate, the crushed materials are unloaded freely through the discharge port at the lower part of the jaw cavity under the action of gravity. With the continuous rotation of the motor, the moving jaw performs periodic crushing and discharging to achieve mass production.
