#### 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.,

#### Optimum choice of the makeup ball sizes for maximum

Optimum choice of the makeup ball sizes for maximum throughput in tumbling ball mills. For the same amount of ball charge, the number of balls in the mill decreases as the ball size increases. Thus, volume fraction of mill filled ball bed [–] J T.
