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
mill shell The industrial scale experiments were performed at varied mill feed rate at constant ball load of 28% In the pilot scale experiments the Magotteaux ball mill at Frank Concentrator was equipped with a Sensomag sensor for measuring the toe and shoulder angles of the slurry and ball load based on the principle of conductance and induction respectively The mill was configured to operate as a RoM ball mill
