DEFINITION

Classification: 241/296

(under subclass 291) Comminuting elements which have comminuting surfaces in the general shape of a disk on a radial face.

(1) Note. Most of the patents classified in this subclass are concerned with the surface characteristics of the disk, i.e., the millstone "dress".

(2) Note. See the notes to subclass 291 for such elements classified elsewhere in the class on the basis of special or combined characteristics.
