### Ball Millan 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 are normally operated at around 75 of critical speed so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input sizemills including a roller press are mostly single-chambered) allowing the use of different sizes of grinding media.

1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill in addition to the nature of the material (grain size hardness density temperature and humidity) the degree of
