Planetary Ball Mill PM 200
The Planetary Ball Mill PM 200 pulverizes and mixes soft, medium-hard to extremely hard, brittle and fibrous materials. It is used wherever the highest degree of fineness is required. Dry and wet grinding can be carried out.
The PM 200 is a bench-top model with 2 grinding station for grinding jars with a nominal volume of 12 to 125 ml.

Princíp funkcie
The grinding jars are arranged eccentrically on the sun wheel of the planetary ball mill. The direction of movement of the sun wheel is opposite to that of the grinding jars in the ratio 1:-2.
The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called Coriolis forces. The difference in speeds between the balls and grinding jars produces an interaction between frictional and impact forces, which releases high dynamic energies. The interplay between these forces produces the high and very effective degree of size reduction of the planetary ball mill.
