Chromium Alloy Casted Grinding Ball Griding Ball of 48-60HRC powder grinding mill
Chromium Alloy Casted Grinding Ball
Forged steel balls are widely used in Cement, Mining, Power Plants, and Chemical industries. The forged ball has a performance of good impact resistance, strong toughness, well wear resistance, and not easily broken and out of circularity. It can increase the productivity of the ball mill and reduce the production cost.
