A pharmaceutical ball mill is a type of grinder used to grind and blend materials while manufacturing various dosage forms. The size reduction is done by impact as the balls drop from near the top of the shell. Ball mills are used primarily for singlestage fine grinding, regrinding, and as the second stage in twostage grinding circuits.

The ball ring mill has a mill housing, a grinding track (6) and grinding balls (7) which are activated by an outside force and run on the grinding track. For each grinding ball a separate pressure mechanism (8) is provided for transmission of the outside force on the grinding balls. Each pressure mechanism has a ball dome surface as pressure surface acting on the grinding balls.

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 ].
