AMIT 135 Lesson 7 Ball Mills
Circuits

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 Rod mills are very similar to ball mills except they use long rods for grinding media The rods grind the ore by tumbling within the the mill similar to the grinding balls in a ball mill To prevent the conditions leading to rod charge tangling the length to diameter ratio is maintained at 1 4 to 1 6
