DEFINITION

Classification: 241/244

(under subclass 220) Apparatus in which the material flows in a generally axial and/or radial direction relative to a rotary surface during the comminuting operation.

(1) Note. See the note to subclass 221 for the line between this group and that providing for devices in which the material flows circumferentially or tangentially of the rotary surface.

91+, 114, 188.1, 206, and 207+, for other comminutors in which the material flows axially and/or radially of a rotary member.

146+, and 161+, for plural devices of this type.
