Working Principle

Comminution according to the Planetary Principle

      The comminution of the material to be ground takes place primarily through the high-energy impact of grinding balls. To achieve this, the grinding jar, containing the material to be ground and grinding balls, rotates around its own axis on a main disk whilst rotating rapidly in the opposite direction. At a certain speed, the centrifugal force causes the ground sample material and grinding balls to separate from the inner wall of the grinding jar. The grinding balls then cross the jar at high speed and further grind the sample material by impact against the opposite jar wall. In addition, impact between the balls themselves on the sample material adds to the size reduction process.

      The instrument can smash and blend various products of different materials and granularity with dry or wet methods. Minimum granularity of grinded products can be as small as 0.1 micron.
