Planetary Mills are ideally suited for fine grinding of hard, medium-hard, soft, brittle, tough and moist materials. The comminution of the material to be ground takes place primarily through the high-energy impact of grinding balls in rotating grinding bowls. The grinding can be performed dry, in suspension or in inert gas.


The extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and therefore short grinding times. The PM 100 is a convenient benchtop model with 1 grinding station. You may also be interested in the High Energy Ball Mill Emax, an entirely new type of mill for high energy input.

Based on a kinematic modeling of the planetary ball mill, the kinematic equations giving the velocity and the acceleration of a ball in a vial in a planetary ball mill are given. The kinetic energy transferred at the collision event, the shock frequency, and the injected shock power are also calculated.


A planetary ball mill includes: a revolution turning arm turned about a revolution shaft rotated by a driving force; mill pots each supported on the revolution turning arm so as to be rotated about a rotation shaft inclined from the vertical direction toward the side of the revolution shaft; and an outer circumferential pot receiver which is disposed fixedly on the upper side of the revolution ...


The interplay between these forces produces the high and very effective degree of size reduction of the planetary ball mill. Across International gear-drive 4-station planetary ball mills have built-in, reverse and timing functions. High energy ball mills grind down material to sub-micron level in minutes.


The kinetic energy imparted to the ball charge in the planetary mill depends on the base plate and vial radii and angular velocities. Attritor or Szigvari ball mills, depending on their size, can be used either for laboratory or commercial ball milling applications and incorporate a rotating vertical shaft with attached horizontal impellors ...
