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.
