Ball Mills

Ball Mill Charge volume The mill power is approximately directly proportional to the charge volume within the normal range When calculating a mill 40 % charge volume is generally used In pebble and ball mills quite often charge volumes close to 50 % are used In a pebble mill the pebble consumption ranges from 3—15 % and the charge has to be controlled automatically to maintain uniform power consumption

Milling Process Defects Equipment

Tool wear can also be reduced by spraying a lubricant and/or coolant on the cutter and workpiece during milling This fluid is used to reduce the temperature of the cutter which can get quite hot during milling and reduce the friction at the interface between the cutter and the workpiece thus increasing the tool life Also by spraying a fluid during milling higher feed rates can be used
