The Planetary Mill PULVERISETTE 5 premium line provides two stations of grinding bowls with 500 ml volume (largest capacity on the market). Each grinding bowl can be filled 1/3 part of the volume ( 170 gr sample). So, if we use two grinding bowls, the optimum capacity is about 170 x 2 340 g per milling process. 3. VIBRA-DRUM Grinding Mills excel over conventional ball, stirred media, or vertical roller mills in both grinding and energy efficiency. The features listed below highlight why our mills are so effective and efficient. Proven energy savings range from 35 to 50% reductions in kW hours per ton of processed material. 5 to 10 times longer media life.
