· The load acted by grinding balls on lignocellulosic biomass is considerably higher, compared to the conventional ball mill and planetary ball mill. Important factors affecting the impact forces acting on the powders are the rate of milling, vibrational frequency, the amplitude of vibration, and the mass of the grinding balls [ 33, 47, 48 ].
Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel.

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 such as silica sand in the planetary ball mill be cause of the great ...
Rotor, hammer and pin mills were found to be good for small scale grinding at a feed rate of g min − 1 under ambient conditions and at g min − 1 for cryogenic grinding (continuous process) whereas the ball mill could be used for a lower feed rate of g min − 1 under ambient grinding; and g min − 1 under cryogenic grinding (batch processes).
