### Planetary Ball Mill PM 200RETSCHshort grinding times

Planetary Ball Mills are used wherever the highest degree of fineness is required.Apart from the classical mixing and size reduction processes the mills also meet all the technical requirements for colloidal grinding and have the energy input necessary for mechanical alloying processes.The extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 -50 of the mill volume and its size depends on the feed and mill size.
