The knife ground sample was used in order to facilitate the grinding process in cryogenic or ball mill. Cryogenic grinding was performed in a cryogenic mill (Spex model 6800, USA) with a selfcontainer liquid nitrogen bath. The precooling time was 5 min and grinding times were in the range from 10 to 50 min (525 cycles of 2 min grinding).

In a ball mill, the particles are ground by repeated impact forces. The material usually needs more than 20 minutes of grinding from mill entrance to outlet, with uncountable impacts take place on this way. Depending on the efficiency of the separator and the Grinding Aid, agglomerates of fine particles are rejected and pass the ball mill again.
