Our grinding ball are widely used for powder preparation and extra-fine deep processing in sectors, such as cement building materials, metal mining, coal paste thermal power plants, chemical engineering, ceramic coating, light industrial paper making and magnetic materials. The cast grinding ball's hardness is high; wearing cost is low; the toughness is very good. So the breakage is few. The surface hardness of ball will be raised further in using the course, and the wear resistance would gather hard to raise mill machine production capacity and raise cement's ratio surface area and reclaim ratio of the extractive mine.
