Rotary striking member with circumferential or tangential flow:
(under the class definition) Apparatus in which the material is subjected to the action of a rotary member which strikes the material a sudden blow to effect comminution including provision to guide the material being comminuted (a) to move generally along the perimeter of the rotary striking member during comminution or (b) to move along a line intersecting the perimeter of the rotary striking member during comminution.

27, for the process of comminuting by use of a rotary striking member.
39, for apparatus in which fluid suspended material is projected against a rotary member which strikes it a blow or in which a rotary member has the additional function of projecting material in a fluid current to effect further comminution against a surface or other portions of the material.
55, for a comminuting device having a rotary striking member combined with gas moving means.
86+, for a comminutor having a rotary moving comminuting surface and a cooperating comminuting surface provided with openings to permit discharge of material.
138, and 154, for the combination of a plurality of rotary striking member comminutors. 221+, and the notes thereto for other rotary comminutors in which the material has similar flow but having no striking member.
275, for a device in which a rotary member merely acts as a projector for material to centrifugally force it against another surface. A device having a rotary member which projects material centrifugally as described and in addition strikes the material a blow to effect a partial comminution before being projected is classified in subclasses 185.5-197.
301, for a feeder or discharger combined with a comminutor where the latter was claimed so broadly as to fail to present a basis for classification in subclass directed to the specific comminutor.
