ABSTRACT:
A fluid energy mill of the confined vortex type for comminuting pulverulent solids, said mill provided with means for measuring the differential pressure between the discharge and the feed of the mill through openings in the chamber peripheral wall and in the discharge means, each opening provided with means for purging into the mill to prevent pluggage thereof and a process for using the mill to grind solid TiO.sub.2 by maintaining a constant differential pressure between 100-600 inches of water.
