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).

The Planetary Ball Mill PM 200 is a powerful benchtop model with 2 grinding stations for grinding jars with a nominal volume of 12 ml to 125 ml. The extremely high centrifugal forces of Planetary Ball Mills result in very high pulverization energy and therefore short grinding times. The PM 200 can be found in virtually all industries where the ...

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.

The temperature of the Emax high energy mill was controlled by an internal water cooling system at a constant fluid temperature of 20 °C. The planetary ball mill does not feature active temperature control; therefore, the mill was always stopped after 5 min of processing for a 15 min break, so the overall processing time was 4 times longer.
