Influence of properties of grinding bowls in the planetary. The polyamide grinding bowl is the softest among the grinding bowls. When the first grinding ball strikes the inner wall during the comminution process, a minimal impression will occur in which at the edge of the impression path, the additional striking grinding balls will slide into and even further shape the grinding path.

To shorten the grinding time, grinding bowls and balls with a higher density and correspondingly higher impact energy can be used. For achieving best grinding results grinding balls are available in 0.1 - 20 mm diameters and in 7 different materials, thus directly preventing contamination of the samples as a result of undesired abrasion.

To achieve this, the grinding bowl, 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 bowl. The grinding balls then cross the bowl at high speed and further grind the sample material by impact against the opposite bowl

2021-6-17 In the Pulverisette 5 Laboratory Planetary Mill, the sample is primarily crushed by the high impact energy of grinding balls, together with friction between the balls and the wall of the grinding bowl. The grinding bowls with sample material and balls rotate around their own axis on a counter-rotating supporting disc. The centrifugal forces caused by the rotation of the grinding bowls and supporting discs work on the contents of the grinding bowls.
