DEFINITION

Classification: 241/84

(under subclass 83) Apparatus in which the comminuting

surface which is provided with the material passages cooperates with a comminuting surface or member which moves relative to it to effect comminution.

(1) Note. Loose grinding body comminutors (e.g., ball or rod mills) provided with perforated receptacles are included in this subclass since the grinding body was considered to present a moving comminuting surface which cooperates with the perforated receptacle. See this class, subclasses 170+, for loose grinding body comminutors with imperforate receptacles.

SEE OR SEARCH THIS CLASS, SUBCLASS:

91+, 94 and 95, for comminutors having perforated comminuting surfaces which cooperate with a stationary imperforate surface or directly with the material (single surface type).

198.1, for other comminutors having cooperating comminuting surfaces.
