Usage

The GUAN WANG Low Chromium Alloyed Cast Grinding Ball is 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, magnetic materials etc. Our grinding ball has the characterisitic of high hardness, good wear resistance and low breakage. The surface hardness and the wear resistant of the grinding ball will further enhance during the operation process. At the same time, it also can increase the production capacity of the mill machine and improve the surface area of cement and the recovery percent of the ore.
