    Abstract: An apparatus for grinding a solid material into a granulated powder formed of particles of generally uniform size includes: a mounting frame; a grinding vessel mounted on the mounting frame which has a grinding cavity defined by a substantially planar floor, a substantially planar ceiling parallel and opposed to the vessel floor, and a substantially circular internal wall; a circular grinding disk positioned within the grinding cavity; and a drive motor or other revolving means for revolving the grinding vessel along an essentially circular path. The revolving motion of the grinding cavity should cause the grinding disk to contact and roll a solid material against the cavity internal wall and thereby grind a solid material contained therein into granules of substantially uniform size.
