Alloy casting grinding ball Alloy casting grinding ball is higher hardness,lower wear rate,good toughness and less are widely used in mining, power plant, cement and magnetic materials industries. In the using process, the surface hardness getting higher and the wear resistant getting strengthen, at the same time, the production capacity of ball mill getting improved.
