Abstract
A matched pair of coaxial milling wheels for small flour mills such as those used in homes. A stationary milling wheel and an adjacent rotatable milling wheel each have a common central axis. Each includes first and second radial surfaces spaced along the axis. The adjacent faces of the wheels have a center cavity extending axially inward and defining the inner periphery of an annular milling face extending to the wheel periphery. Complementary grooves are formed in the milling face of both wheels to feed grain radially outward from the central cavities and to assist in cracking and grinding the particles to a fine state. The wheels are formed integrally from fired stoneware and have machined flat annular rims about the milling faces to assure accurate final grinding of the particles before they exit from the space between the two wheels.
