Crusher Alloy Hammer Head for Coal Mine

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.
