DEFINITION

Classification: 241/198.1

Cooperating comminuting surfaces (e.g., jaw crusher):

(under the class definition) Apparatus in which the comminution of the material takes place between two relatively moving surfaces which cooperate to effect the comminuting operation.

(1) Note. A number of classes provide for the treatment of material between relatively moving cooperating surfaces to change the dimensions, particle size, or other properties of the material. A partial list of such classes as were considered to present analogous subject matter will be found below under "Search Class".

274+, 277+ and 283, and the notes thereto, for a device in which the comminution is effected by the cooperation of the material directly with a single surface.
