Abstract: Compositions and methods pertaining to the ultrafine grinding of soft materials are disclosed. In one embodiment, a method comprises the step of mixing a soft material with an additive to form a mixture. The method further comprises raising the temperature of the mixture to at least the glass transition temperature of the soft material.

Ball Mills are the most effective laboratory mills for rapid batchwise comminution of medium-hard, soft, brittle, fibrous, temperature-sensitive and moist samples down to the finest particle size. The comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding ...
