Grinding balls refer to materials such as bauxite, roller powder, industrial alumina powder, and high-temperature calcined Alpha alumina powder as raw materials, after batching, grinding, powdering (pulping, mud making), forming, drying, and burning Ball stone produced by the process of finishing and other processes, mainly used as a grinding medium. It has 60%~65% Al2O3, 75%~80%Al2O3,90% above high alumina oxide.
