LM PBM4000 Planetary Ball Mill

Like in a planetary system the grinding jars rotate on a orbit around the center. This rotational movement is the self-rotation of the grinding container. The resulting centrifugal and acting acceleration forces lead to a strong grinding effect. Furthermore there are forces working according to the Coriolis acceleration. The result is an intensive grinding effect between the grinding balls and the sample.

• Adjustment of grinding duration : digit adjustable
• Dimenstions closed W x D x H : ca. 759 x 645 x 550 mm
• Effective sun wheel diameter : 360 mm
• Sun wheel speed : 50 – 400 min-1
• Electrical requirements : 200-240 Volt 50/60 Hz
• Feed size maximum : 10 mm
• Max end-fineness : 1μm; 0,1μm for colloidal grinding
• Number of grinding jars : 4/8
• Max volume of each grinding jar : 500 ml
• Min volume of each grinding jar : 10 ml
