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.

The Mechanism and Grinding Limit of Planetary Ball
the rate of grinding in the planetary ball mill is known to be about 100 times greater than that in a tumbling ball mill and about 50 times greater than that in a stirred ball mill2). Another result is given in Fig. 3, from which it is seen that even small glass beads with a low density can be used to grind hard materials ...

THE OPTIMAL BALL DIAMETER IN A MILL
2012515 The basic condition, which must be met while grinding the material in a mill is that the ball, while breaking the material grain, causes in it stress which is higher than the grain hardness (Bond, 1962; Razumov, 1947; Supov, 1962). Therefore, for the biggest grain size, it is necessary to have a definite number of the biggest balls in the charge,
