Planetary Mills - Milling and Sizing - Home – fritsch.de

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.

planetary ball mill (Pulverisette 6, Frisch, Germany). Ball milling was conducted at 300 rpm with cycles of a 10 min milling plus a 10 min pause. The milled bagasse was screened through a 0.25 mm sieve to remove large particles and powder agrregates. The milling times were 30, 60 120 and 180 min resulting in four bagasse size ranges.
