Product Description

Rotary cutting, forging and rolling grinding steel ball is used for grinding materials in mechanical equipment such as ball mill, tower mill and ultra-fine grinding. It is especially suitable for wet grinding conditions. The specific wear resistance varies according to the composition and hardness. Continuous quenching and tempering process equipment is adopted for heat treatment, so that the performance of steel ball has better stability.
