With the widespread adoption of new dry-process cement production technology, limestone crushing equipment is evolving towards larger scales. In this context, large hammer crushers, known for their high crushing ratio, have gained extensive application. As a critical hammer crusher wear parts, the manufacturing process and performance of large
During high-speed rotation, large are subjected to tremendous impact forces from multi-ton limestone, demanding exceptional toughness and wear resistance from the material. Austenitic manganese steel has emerged as the material of choice for hammer heads due to its superior properties. However, traditional high manganese steel suffers from drawbacks such as low yield strength and susceptibility to plastic deformation. To address these issues, the industry has widely adopted the addition of approximately 2% chromium (Cr), effectively enhancing the material's yield strength and wear resistance.
