Ball Mill Media Size

Criteria in Selecting Size of Zirconia Grinding Media · Larger sized media are more efficient in breaking up large particles · Smaller media are more efficient in milling smaller particles because of higher effective contact area · Larger media sizes are favored in many conventional ball mills Smaller sizes are more appropriate for attritors

Costs Media that may be 2 3 times more expensive may last considerably longer and therefore be well worth the extra cost over the long run The type of mill also can affect the selection of grinding media Ball Mills use very large media while Attritors employ media ranging in size from 1/8 to 1
