Ball Mills – fritsch.de

Ball Mills are the most effective laboratory mills for rapid batchwise comminution of medium-hard, soft, brittle, fibrous, temperature-sensitive and moist samples down to the finest particle size. The comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding bowl respectively the mortar.

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

Grinding Down to the Nanoscale with Planetary Ball .

The mill derives its name from the unique kinematics wherein the grinding bowls are mounted on a rotating "sun" disk that rotate in the opposite direction around the disk centre. Because of this, the samples are quickly and effectively comminuted by impact, frictional and shear forces resulting from ball-to-wall and ball-to-ball collisions.
