PM GrindControl RETSCH control for your ball mill

Pressure and temperature measuring system In order to understand the processes which occur during grinding with ball mills (e.g. chemical reactions, phase changes), it is helpful to record the most important thermodynamic parameters: pressure and temperature. Planetary ball mills are frequently used for the development of new materials by mechanical alloying due to their high energy input.

Ball Mills fritsch.de

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
