no problems of attritional heat. Cen trifugal force keeps over-sized particles in the grinding zone. Cyclone action in the central section classifies and collects the fines for bagging. Instant accessibility, easy cleaning. Micronizer* Grinding Machines come in seven sizes — each one constructed for quick accessibility and easy main tenance (typified by the "OPEN DOOR" design in other Sturtevant equipment). Grinding chambers range from the 2 in. laboratory size with Vz lb. per hr. capacity to the 30 in. size which handles up to 3000 lbs. per hr.

Look at the record! 30 inch model re duced titanium dioxide t o 1 micron and finer at solid feed rate of 2250 lbs. per hr. 24 inch model reduced D D T ( 5 0 % ) to 3.5 average microns — 1200-1400 lbs. per hr. 8 inch model reduced Procaine—Penicillin—to 5 to 20 microns—up to 20 lbs. per hr. Couldn't you use milling performances like these? No moving parts. The particles grind each other. High-speed rotation and violent grinding impact of particles are caused by jets of compressed air or steam at angles to the periphery of the shallow grinding chamber. There are
