### Ball Mill an overview ScienceDirect Topics

The degree of filling the mill with balls also influences productivity of the mill and milling efficiency. With excessive filling, the rising balls collide with falling ones. 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.

### Ball mill- what is the % of filling by balls and % of

Ball mill- what is the % of filling by balls and % of filling by materials ? ball mill size dia=2 meter, length 8 m, inner dia= 1.888 m,material to be grinded= illuminate, ball size= 20,30,40 mm

### A Method to Determine the Ball Filling, in Miduk Copper

to ball filling variation in the mill. The results obtained from this work show, the ball filling percentage variation is between 1.2– 3.7% which is lower than mill ball filling percentage, according to the designed conditions (15%). In addition, acquired load samplings result for mill ball filling was 1.3%.

### How to Improve the Ball Filling Rate of Ball Mill

ball mill In order to remain the filling amount, type and ratio of balls unchanged. In the daily production of ball mill, there should be a reasonable adding of balls, so that the ball type and ball loading ratio can reach balance. This requires the reasonable filling steps for the equilibrium ball.
