ABSTRACT:
Apparatus for comminuting materials to extremely fine size includes a circulating stream jet mill and a discrete but functionally interconnected and interdependent rotating anvil-jet impact mill. New material is injected into the impact mill against a rotor, and the partly comminuted material is transferred to the jet mill with vortex feed into the jet mill. Uncomminuted material in the jet mill is reinjected into the impact mill. The two mills transfer the material back and forth until the particles are comminuted, classified, and removed from the jet mill. The anvil-jet mill is provided with stationary anvils and support for turning the rotor at increased velocity.
