Ball mill A typical type of fine grinder is the ball mill A slightly inclined or horizontal rotating cylinder is partially filled with balls usually By this the material bed is compacted to a solid volume portion of more than 80Ball Mill Operating principles components Uses Ball Mill The balls which could be of different diameter occupy .
Generally filling the mill by balls must not exceed 30–35 of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length. Optimum ratio between length L and diameter D L D is usually accepted in the range 1.56–1.64.
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.
