    This rotational movement is the selfrotation of the grinding container. The resulting centrifugal and acting acceleration forces lead to a strong grinding effect. Furthermore there are forces working according to the Coriolis acceleration. The result is an intensive grinding effect between the grinding balls and the sample.

  • Ball mill Wikipedia

    A ball mill is a type of grinder used to grind and 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. A ball mill consists of a hollow
