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 than3% moistureto minimize ball coating, or slurry containing20–40% water by weight.

Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes. A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel. The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio:1:-2 or 1:-1 or else).

Sep 01, 2013· Fig. 8 shows the optimum composition of the make-up ball sizes for various feed sizes as a function of the size reduction ratio, R. Because mixtures of two balls (50.8 mm and 25.4mm ball) are always found to be optimum, the results are plotted with the ordinate being the fraction of 50.8 mm balls.
