Abstract

A pulverizing system for reducing the size of material including a body, a pair of rotating members at least partially disposed within said body, and at least one impeller arm attached to each of said rotating members. The impeller arm attached to one of the rotating member throws material into a substantially head-on collision with material thrown by the impeller arm attached to the other rotating member.
