### AMIT 135: Lesson 7 Ball Mills & Circuits Mining Mill

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,

Ball mills characterized by high energy consumption. When the mill idles, the energy consumption is approximately equal to the energy consumption with full mill capacity. Therefore, the work of the mill with partial load conditions is unprofitable. Energy consumption for ball mills is a function of many factors: the physical properties of the ground material — its specific gravity and

01/01/2016· Grate discharge mills give less excessive grinding compared to overflow mills and are best suited to grinds to 150–250 μm. In Figure 7.2 C, the discharge opening is at the centre of the mill, while the feed is from both ends of the mill. The mills are therefore designated as a Centre Periphery Discharge mill. The diameter of the feed trunnion is slightly smaller than the discharge trunnion
