ABSTRACT:
In an upper portion of a housing is a material-receiving chamber below which is a lower portion that defines a comminution chamber. An apertured screen is disposed in the bottom of the latter for permitting the gravity discharge of material which has been comminuted. Mounted horizontally within the lower portion is a shaft, and that shaft is driven in rotation. A plurality of hammers project rigidly outward from the shaft with the hammers being arranged in an assembly which includes a plurality of hammer-carrying elements individually spaced successively along the shaft. The hammers on each element are circumferentially spaced successively around the shaft. Moreover, each hammer includes a material-impacting face of concave arcuate conformation in the plane of movement of the hammers.
