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.

1.The mixing chamber is of chilled structure with quick and better heating/cooling effects. The inner wall is coated with hard chrome for long service life.. 2.Build-up welding of hard alloy for the two, three, four ridge top and two sides of the rotor, all the working surface are coated with hard chrome, good appearance and abrasive resistantce, the cooling/heating medium can pass through the hollow of the tangent linear type, mesh type, and synchronization type rotor. 3.Constant hydraulic pressure seal structure is used for the top of the rotor and the seal effect is good with long service time thanks to high pressure lubrication automatic alarm for used up of oil. 4.The upper bolt relieves the pressure automatically to protect the machine and for long service time if the machine work for too long time under overload condition. 5.The working surface of up and down bolts are coated with hard chrome, good appearance and abrasive resistance. The cooling/heating medium can pass through the inner hollow of down bolt. 6.A rotary oil cylinder is used for the discharge door, smooth running and accurate positioning. 7.Use two shafts put-out hard teeth reducer and gear coupling or "+" type universal joint, the transmission is smooth with high effciency, low noise level and long service life.
