feed stream in hammer mills for grinding tough materials. However, liquid nitrogen is seldom used in jet milling opera-tions due to the swift heat exchange between the material and the grinding gas. The grinding gas heats up the super-cooled feed stream, and the material loses its brittleness when it absorbs this heat. Stickiness.

Planetary Mills are ideally suited for fine grinding of hard, medium-hard, soft, brittle, tough and moist materials. The comminution of the material to be ground takes place primarily through the high-energy impact of grinding balls in rotating grinding bowls. The grinding can be performed dry, in suspension or in inert gas.

Terephthalic acid and chromium salts [Cr(NO 3) 3 ·9H 2 O or CrCl 3 ·6H 2 O] were milled in a ball-miller at 30 Hz for 30 min and then heated in an autoclave at 190 °C for 3 h. XPS spectra determined for the both MOFs confirm the presence of Cr and exclude the presence of Fe that could be introduced from the grinding jar and balls.

The Operating Principal. P ulverization takes place in the central chamber of the Micron-Master® jet energy mill as the process material is driven at near sonic velocity around the perimeter of the toroidal chamber by multiple jets of air or steam. No grinding media is involved. Size reduction is the result of the high-velocity collisions between particles of the process material itself.
