How to improve working efficiency of ball mill

Control Feed Size. The particle size of the material entering the ball mill is controlled between 25-15 mm (the diameter of the ball mill is different for different feed sizes). Excessive rules will cause the ball mill to have too much fine material during the grinding process and cannot achieve the friction between the material and the material.

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.
