Ball Mill An Overview Sciencedirect Topics

Generally filling the mill by balls must not exceed 3035 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 156164

The Operating Principle Of The Ball Mill

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 hardness the degree of drum filling by grinding balls the number of drum rotations etc ball mills have low efficiency no more than 15
