Features of Forging Steel Grinding Balls

The materials of the grinding steel balls can be customized.
The steel balls are transported directly to the online heat treatment equipment, which is specially designed for quenching and tempering. It makes sure steel balls can obtain high and uniform hardness.
Finished forging steel balls are characterized with precise size, good wear resistance and mechanical properties, which is a kind of high combined efficiency grinding media.
