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 grinding jar, where size reduction takes place primarily by pressure and friction.

 · Feed to ball mills can be as large as 2.5 to 4 cm (1 to 1a in) for very fragile materials, although the top size is generally 1 cm (a in). Most ball mills operate with a reduction ratio of 20 to 200:1. The largest balls are typically 13 cm (5 in) in diameter.

One method of size reduction is the ball mill. The ball mill is a type of grinder that grinds materials into fine powder. When heavy balls of material fall on and crush the material being milled, grinding occurs. The raw material's particle size decreases as a result of continuous collision. The size and weight of the ball, as well as the ...
