ball mill cataracting - Mine Equipments. 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.

Grinding Media Charge Motion inside Mill

It is seen that a fourfold variation in the coefficient of friction produces, for a given speed of rotation, but a negligible variation in the maximum mill filling which will permit cataracting. Thus, it is probably safe to say that these results, shown graphically in Fig. 2.19, are applicable to any practical mill with an accuracy sufficient for any normal purpose.
