Ball Mill an overview ScienceDirect Topics

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.

How to calculate ball to powder ratio? ResearchGate

But efficiency of ball milling depends upon many factors like Ball dia, PCA used, Rotational speed, type of charge. For a ductile charge it should be better with 15:1.

Best way to determine the ball-to-powder ratio in ball

The maximum power draw in ball mill is when ball bed is 35-40 % by volume in whole empty mill volume. Considering that ball bed has a porosity of 40 %, the actual ball volume is considered to be
