Fritsch Pulverisette 5/2 classic planetenkogelmolen 2 posities

Fritsch planetenkogelmolen Pulverisette 5 met 2 posities

• Principe: doordat de maalbeker op een schijf juist omgekeerd draait als om zijn as, rollen de kogels langs de wand en slaan vervolgens door de beker tegen de overliggende wand.

Toepassingen

• Geschikt voor: het zeer fijn malen van hard tot zacht materiaal, droog of in suspensie.
• Geologie, scheikunde, mineralogie, keramische industrie, bouwmaterialen industrie, metallurgie, elektronische industrie, glasindustrie, nucleair onderzoek en bodemonderzoek.

The comminution of the material to be ground takes place primarily through the high-energy impact of grinding balls. 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 wall. In addition, impact between the balls themselves on the sample material adds to the size reduction process. Due to the rotational speed of the main disk – up to 400 rpm – achieves the PULVERISETTE 5 classic line a centrifugal acceleration of up to 22 g.
