For achieving maximum capacity of the ball mill, the ball charge should be equal to about ______________ percent of the ball mill volume?
Correct answer: C. 50
- A. 10
- B. 25
- C. 50
- D. 75
Explanation
A ball charge of about 50% of the mill volume gives the greatest practical capacity because it provides many grinding contacts without excessively reducing the free space for movement of the material. Much lower or higher charges reduce effective grinding.
