The hammer head of the crusher should be accurately defined as the hammer head of the hammer crusher. The hammer head is one of the core components of the hammer crusher. It is arranged on the hammer shaft of the crusher rotor. The hammer head hits directly when the crusher is running at high speed. The material is finally broken into a suitable material particle size.
According to the manufacturing process, the crusher hammers on the market can be divided into two types: casting and forging, but their wear resistance is different. Due to the crushed materials, the head needs good wear resistance and the handle needs sufficient toughness. Usually alloy steel, high manganese steel, cast steel and high chromium cast iron bimetallic composites are used for forging or casting. The corresponding heat treatment process is more economical. According to the material, the hammers of the crusher can be divided into types: high manganese steel hammers, bimetal hammers, high chromium hammers, composite hammers, large gold teeth hammers, and medium chromium alloy hammers. The main factor is the content of silicon dioxide. The technology in modern industry shows that the use of cemented carbide hammers performs well in wear resistance.
Our company has many years of experience in the production and sales of composite hammers for crushers. Special composite casting technology is used in the manufacturing. The striking parts of the hammers are made of high-chromium cast iron wear-resistant materials, and the hammer handles are made of wear-resistant alloy steel with good impact resistance and toughness. The material, through the split-inlaid composite pouring method, ensures the wear resistance and impact toughness mechanical properties of the high chromium composite hammer head. Compared with the manganese steel hammer head, the life of the hammer head produced by our company can be increased. 3-5 times.
