The interplay between these forces produces the high and very effective degree of size reduction of the planetary ball mill. Planetary mills with a single grinding station require a counterweight for balancing purposes. In the Ball Mill PM 100 CM this counterweight can be adjusted on an inclined guide rail.

Generally, every crusher machine is not the same, here are several common crusher size reduction ratio: The impact crusher size reduction ratio is 20 to 1. The vertical shaft impact crusher size reduction ratio is 4-8 to 1. The vertical roller mill size reduction ratio is 2-2.5 to 1. The hammer crusher size reduction ratio is 20 to 1.

Planetary Ball Mill technology tween these forces produces the high and very effective degree of size reduction of the Planetary Ball Mill. The PM 100 CM operates with a speed ratio of 1:-1 (centrifugal mode). The centrifugal forces pro-duced by the rotation movement the sample and the grinding balls against the inner wall of the

As the size reduction ratio increases, the optimum ball ratio moves towards more small balls. At the finest grinding with a size reduction ratio of 128:1 (Fig. 7d), a 50.8 mm/25.4 mm ball mix at a 13:87 ratio was found to be the optimum mix. This indicates that the finer the product size, the higher the proportion of smaller balls that is required.

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.
