How much ball quantity should be controlled in the

2019-7-10  The amount of ball installed in the ball mill refers to the number of steel balls in the cylinder when the ball mill grinds. In order to ensure the grinding efficiency of ball mill, the type selection test should be carried out according to the actual situation of concentrator, and the number of ball loading in accordance with the situation should be calculated.

Ball Mills - an overview ScienceDirect Topics

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
