Each type of hammer currently being used in hammer crushers has its own individual disadvantages. High manganese steel hammers present wear problems, high chromium cast iron hammers are fragile, and general composite hammers are plagued by the "eat handle" phenomenon. As such, an application study was conducted on composite materials and production processes. By using a bimetallic composite casting hammer, different materials can be used for each role such that the advantages of each metal are fully utilized. The handle and end of the hammer adopt the distinct characteristics of its component low alloy steel and high chromium cast iron respectively, thereby improving the original double-metal composite technology. With the improved casting process, the interface location has changed. Thus, while some additional difficulties are involved in the production process, it should be ensured that a completely metallurgical bond is formed during actual implementation.
