Crushers and mills are made from metal alloys and then weld-assembled, stress-relieved, and subjected to non-destructive testing (NDT). High-chromium alloy irons are treated in furnaces with programmable controls to achieve consistent properties and a longer wear life. Crusher machines and grinding mills that are lined with a high-carbide layer are designed to resist abrasion and increase wear life. Cutting surfaces remain sharp throughout much of the life of the crusher part, increasing shredder efficiency. Crusher machines and grinding mills for gyratory crushers, cone crushers, jaw crushers, roll crushers, hammer mill crushers, and impact crushers are sometimes made from proprietary manganese steels. The performance of any crusher or mill with a given material is highly dependent on the characteristics of the material. Conversely, many materials process better in one design of machine than another. Selection of the proper crusher or mill for an application is material-specific; the correct choice of equipment can only be made after testing...
