DEFINITION

Classification: 241/277

(under the class definition) Apparatus in which material is presented for comminution to a single comminuting surface which has a simple rotary motion.

91+, for identical devices in which the comminuting surface is provided with passages for the material.

136, and 151, for plural devices of this type arranged for parallel or series-parallel flow of material. 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 plural devices of this type arranged for series flow of material.

185.5, through 197, for rotary comminuting devices provided with members which strike the material. 220+, for rotary surfaces which cooperate with other surfaces to effect comminution.
