(under the class definition) Apparatus in which material is presented to a single comminuting surface which has a reciprocating motion relative to the material.
SEE OR SEARCH THIS CLASS, SUBCLASS:
94, for identical devices in which the comminuting surfaces are provided with passages for the material.
136, and 151, for a plurality of such devices arranged for parallel or series parallel material flow therethrough. Apparatus in which a plurality of distinct columns of material are fed against a common surface was considered to present a plurality of comminuting zones in parallel.
152.1+, for a plurality of such devices in series.
205, 237, 250, and 262+, for devices having surfaces which reciprocate relative to a cooperating surface. SEE OR SEARCH CLASS
