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.
