ATTRITORS AND BALL MILLS HOW THEY WORK Robert E.

Ball mills can blend and grind at the same time, yielding a fine, intimate mixture. Conventional ball mills are usually limited to a particle size of 1µ after one hour of grinding since gravity causes the particles to fall out of the grinding zone (between the media). Milling can be done either wet or dry, although it is generally possible to get smaller particle sizes wet than dry.
