Overview

Ideal for large quantities

      The Planetary Mill F-P400 with 4 working stations delivers fast and reliable, due to the particularly high-energy effect of the grinding balls, loss-free grinding results of hard, medium-hard, soft, brittle, tough and moist materials down to colloidal fineness. Depending on the desired final fineness, can the grinding be performed dry, in suspension or in inert gas.

      Besides for comminution, the Planetary Mill can be utilized for mixing and homogenizing of emulsions and pastes or for mechanical activation and alloying in material research. The fixed transmission ratio, rotational speed regulation and precision quartz timing ensure exactly reproducible grinding conditions.

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.

For homogenisation

Please note: For the Planetary Mill, you require at least 4 grinding jar of your choice and the corresponding number of grinding balls. The grinding jar material must also be harder than the material to be ground. In normal cases, grinding jars and balls of the same material are used. To shorten the grinding time, larger or heavier grinding jars and grinding balls with a higher density and correspondingly higher impact energy can be used. Please take note of the useful capacity, this is not identical with the jar volume!
