DEFINITION

Classification: 241/107

(under the class definition) Apparatus in which a plurality of rotary or oscillatory surfaces cooperate with the same portion of another surface so as to comminute material.

(1) Note. In the titles and definitions below, the term "plural surfaces" has been used to denote the plural rotary or oscillatory surfaces, and the term "common surface" to

denote the single surface, or portion of a surface with which the plural surfaces cooperate.

(2) Note. In general, those devices in which a plurality of surfaces are mounted rigidly (sectional surfaces) to rotate about a single axis have not been considered to present plural surfaces to the common surface and have been classified as if a single surface were so presented. If the plural surfaces are adapted to move relative to the axis during comminution they have been included in this group. An exception to this rule was made in the case of devices in which a unitary member carries a plurality of striking members which cooperate with another surface. These have been considered to present a single surface and have been classified as impact mills for which see this class, subclasses 185.5-197.

(3) Note. The plurality of rotary or oscillatory surfaces in the devices of this group must be mounted so as to be restricted in their movement. See this class, subclass 170, for devices in which a plurality of loose comminuting bodies cooperate with a common surface to effect the comminution.

74, for chasers provided with an annular screen surrounding the comminuting zone to prevent the discharge of uncomminuted material. 79+, for chasers in which the common surface is provided with an annular perforated extension thereof to separate the material.

83+, for chasers in which one or more of the comminuting elements are perforated.

103+, for ball chasers in which rolling members are supported and driven by surfaces common to all of the rolling members.

198.1, for cooperating surface comminutors in which a single surface which cooperates with another surface may have a movement corresponding to some of the motions of the plural surfaces provided for in this group.
