Mill suppliers can line ball mills with ceramics to reduce contamination from abrasive materials, but mill media wear is constant, which also can contaminate a product. Jet mills. Until the introduction of jet mills in 1936, dry grinding in the subsieve range of 625 mesh (20 microns) to 2,500 mesh (5 microns) was impractical.

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.
