DEFINITION

Classification: 241/103

(under the class definition) Apparatus in which rolling members which effect the comminution are mounted in contact with a plurality of relatively moving surfaces so as to be frictionally driven thereby and at least one of the surfaces forms the support for the roller members.

(1) Note. These devices are commonly referred to as "ball chasers".

(2) Note. For the most part, the devices herein are provided with a plurality of roller members, but those including only a single roller are found in this group.

SEE OR SEARCH THIS CLASS, SUBCLASS:

107+, for similar devices in which a plurality of rollers are supported by means other than one of the frictional drive surfaces.

173+, for similar devices in which rolling comminuting bodies are moved relatively to a receptacle by pusher members rather

than being frictionally driven between relatively movable surfaces.
