introduction:

Low chromium alloy cast balls are widely used in cement, building materials, metal mining, coal slurry thermal power, chemical engineering, ceramic coating, light industry, papermaking, ultrafine powder preparation of magnetic materials and other industries and further processing.Products high hardness, low wear, good toughness and less broken, in the process of using sphere will further improve the surface hardness, wear resistance, and can improve the grinding machine production capacity, improve cement specific surface area and concentrate recovery rate.
