Mixer is a kind of construction machinery, which is mainly used to mix cement, sand, all kinds of dry powder mortar and other building materials. This is a machine with a shaft with blades rotating in a cylinder or tank to stir and mix a variety of raw materials into a mixture or suitable consistency. There are many kinds of mixers, including forced mixer, single horizontal shaft mixer, double horizontal shaft mixer and so on.
working principle
The mixer is determined by multiple parameters. It is impossible to describe a mixer with any single parameter. Shaft power (P), blade discharge (q), head (H), blade diameter (d) and mixing speed (n) are five basic parameters to describe a mixer. The discharge volume of the blade is directly proportional to the flow standard of the blade itself, the first power of the blade speed and the third power of the blade diameter. The shaft power consumed by mixing is directly proportional to the specific gravity of the fluid, the power standard of the blade itself, the third power of the rotating speed and the fifth power of the blade diameter. Under the condition of certain power and blade form, the discharge volume (q) and pressure head (H) of the blade can be adjusted by changing the matching of the diameter (d) and speed (n) of the blade, that is, the large-diameter blade with a mixer with low speed (ensuring constant shaft power) will produce higher flow effect and lower pressure head, while the small-diameter blade with high speed will produce higher pressure head and lower flow effect. In the stirred tank, the only way to make the micro clusters collide with each other is to provide sufficient shear rate. From the mixing mechanism, it is the existence of fluid velocity difference that makes the fluid layers mix with each other.

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. Coal machine parts manufacturer Henan Shuanzhi production of various types of forging hammer head, crushing shaft group. More coal accessories small knowledge, welcome you to continue to pay attention to Henan Shuangzhi.

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.
Jaw Crusher custom Industrial jaw crusher custom Jaw crusher manufacturers Ding Bo heavy industry jaw crusher mainly includes PE jaw coarse crusher, PEX fine jaw crusher, PEW European version jaw crusher and other models.� Jaw crusher is commonly known as jaw crusher. The jaw crusher produced by Ding Bo Heavy Industry mainly includes steel plate casting and other types. The crushing cavity is composed of two jaw plates, the moving jaw and the static jaw.� Complete the crushing process of the material.� Industrial Stone Crusher Machine is currently widely used in the quarry, mine manufacturing, building materials, highway, railway, water conservancy and chemical industry, construction waste treatment, and other industries in the crushing of various ore and bulk materials.� The highest compressive strength of the crushed material is 320Mpa. Stable structure and reliable performance � � � � � The bearing seat adopts an integral cast steel structure, which avoids unnecessary burdens on the frame caused by the two-piece bearing chamber and improves the stability of the overall structure. In addition, the heavy eccentric shaft is processed by forging billet, which makes the PEW series jaw crusher have extraordinary reliability. working principle � � � � � � During the working process of the Stone Crusher Machine, the motor drives the eccentric sleeve to rotate through the transmission device. The moving cone is rotated under the force of the eccentric shaft sleeve. The section of the moving cone near the static cone becomes the crushing cavity, and the material is subject to the moving cone. And static cone crushed and crushed repeatedly. When the moving cone leaves the section, the material that has been broken to the required granularity there falls under its own gravity and is discharged from the bottom of the cone.
