Grate Discharge Ball Mills have shown 25% to 45% more tonnage ground and a substantial reduction in power consumed per ton of material compared size for size with overflow mills. To illustrate the characteristics of various type mills we have shown the types of discharge for rod mills and ball mills. There are essentially four types of rod mill ...
