Coal Mining Crusher Hammer Head

The hammer head used in coal mine has abrasion resistance and impact resistance. The hammer head is an important working part of the crusher. Its production capacity is determined by its shape and material quality. Generally speaking, the hardness of the material is higher, the hardness of the hammer head material is higher, the hardness of the hammer head is higher, the greater the wear resistance of the hammer head is greater, the impact load of the hammer head is greater, the higher the requirement for its toughness. The wear of hammers is related to many factors, such as material, underground environment, weight, product quality, etc. The maintenance and maintenance of each part of the hammer head is very important, as the core parts of the hammer head, not only the market demand is large, the crusher hammer head wear resistance also to meet the standard. Henan Shuangzhi mainly produces crusher accessories such as crushing shaft group, hammer head, cutter tooth base, fixed base, fastening assembly, belt pulley and so on.

34P12-15 cutter teeth matching 34P12 crushing shaft set, the main machine is PLM4500 wheel crusher. Special fastening bolts and nuts are used in the golden cauldron for matching the cutter tooth base after forging, and the bolts and nuts are stuck with anti-loose gaskets. PLM4500 wheel crusher is installed at the fixed position in the landing section of SZZ1350/525 channel bridge transfer machine. When transporting coal, the crushing shaft of the crusher drives the crushing knife teeth to rotate, impact and cut large pieces of coal, and crush them into the required lumpness. The 34P12 crushing shaft set is equipped with 34P12-01 shaft, 34P1201 bearing seat, 34P12-04, 34P12-05, 34P12-15 cutter teeth and other accessories. If you need broken shaft group, please contact Henan Shuanzhi, welcome to visit the factory.

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 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.

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 Shuanzhi.

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.
