Ball mill a typical type of ball mills normally operate with an approximate ball charge of 30.Fluid mechanics of slurry flow through the grinding the grinding efficiency of semi autogenous milling or ball milling depends on the tumbling motion of the total charge within the mill.
The higher break point is reserved for harder wet grinding materials such as enamel as well as dry materials.This angle of break is also determinate upon the size of the mill.Since grinding actions in a larger mill are more severe than that of a smaller mill, the angle of break should be lower for the larger mills than the smaller.
