Agitator Speed an overview ScienceDirect Topics

The attrition mill agitator rotates at speeds ranging from 60 rpm for production units to 300 rpm for laboratory units and uses media that range from 3 to 6 mm while ball mills use large grinding media usually 12 mm or larger and run at low rotational speeds of 10 50 rpm Power input to attrition mills is used to agitate the medium not to rotate or vibrate heavy drums Therefore specific
