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.

Hence, planetary ball mills employ the combined action of two centrifugal fields which results in a nonuniform acceleration within the grinding pots. Generation of both Coriolis and centrifugal forces increase the kinetic energy of the grinding balls up to 100 times the gravitational force, causing higher impact energy between the grinding ...
