It can also be used for mixing and homogenising of emulsions and pastes. Grinding capacity of up to 8 samples per operation. Category: Crushers, Pulverizers, Grinders. Description. Technical details.
A planetary ballmill (Pulverisette7, Fritsch, Germany) was used for ballmilling. The milling machine was equipped with two mill pots (made of zirconium dioxide, inner volume of 45 cm 3 each). The grinding ball was composed of zirconium dioxide balls, and the balltomaterial mass ratio was maintained at % (70 g of balls to 4 g of material).
Planetary Mills are ideally suited for fine grinding of hard, mediumhard, soft, brittle, tough and moist materials. The comminution of the material to be ground takes place primarily through the highenergy impact of grinding balls in rotating grinding bowls. The grinding can be performed dry, in suspension or in inert gas.
