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 (non-spherical, irregularly shaped and mixed-size 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% ...

Heavier oversized particles are held in the grinding chamber by centrifugal force, until micronized to a desired size. Feed particle size is critical, restricted by the size of the feed injector. For mills of 200-300 mm, the feed size can be a maximum of 1.5 mm. For smaller-size mills, the feed size is …

The Operating Principal. P ulverization takes place in the central chamber of the Micron-Master jet energy mill as the process material is driven at near sonic velocity around the perimeter of the toroidal chamber by multiple jets of air or steam. No grinding media is involved. Size reduction is the result of the high-velocity collisions between particles of the process material itself.
