### Effect of Grinding Media on Milling

The rate of grinding is not the whole story, however, for it has been shown, from theoretical considerations by Rose and from tests on industrial mills by Engels, that ball and liner wear is reduced by the use of soft metal for the balls and mill shell when very hard materials are to be ground. Thus, although the rate of grinding is reduced, the replacement costs of the balls, and also ...

### Ball Mills - 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.

### Ball Mills - Mine Engineer.Com

A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a ...
