The Operating Principal. P ulverization takes place in the central chamber of the MicronMaster® 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 highvelocity collisions between particles of the process material itself.
