DEFINITION

Classification: 241/134

(under the class definition) Apparatus in which there is provided a plurality of comminuting zones through which the material flows in parallel paths.

(1) Note. Devices in which the material flows serially and also in parallel paths through plural comminuting zones are to be found in this group. Where the flow is solely from one comminuting zone to another in succession, the patents have been placed in subclasses 152.1+.

SEE OR SEARCH THIS CLASS, SUBCLASS:

42, and 44, for devices including fluid applying means in connection with means for causing parallel material flow through plural comminuting zones.

75, for devices in which the material passes through plural comminuting and separating zones in parallel.

104, 105, 108, and 115+, for comminutors of the type there provided for arranged for parallel material flow.
