Wet Circulation Production Mills Union Process

Wet Circulation Production Mills Union Process

The circulation grinding Attritor ("Q" machine) is a combination of an Attritor and a large holding tank which is generally about ten times the size of the Attritor. The unique principle of the "Q" Attritor is the high circulating (pumping) rate, which results in a faster grind and a narrower particle size distribution.

Ball Mill Loading Dry Milling Paul O. Abbe

Ball Mill Loading Dry Milling Paul O. Abbe

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (nonspherical, irregularly shaped and mixedsize media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%15% above the ball charge for total of 23% ...

Effect of ball and feed particle size distribution on the milling ...

For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower.
