ABSTRACT:
A matched pair of milling wheels for use in home grain mills includes a stator and a rotor. Each wheel is ideally composite, with a metal casting supporting a peripheral ring of cast stone. When the wheels are mounted in a mill with their peripheral grinding surfaces juxtaposed, their interior sections define a central cavity which functions as a crushing section. The crushing section contains opposed cutting teeth constituting means for primary shearing and grooves spaced between the cutting teeth constituting means for secondary shearing action. The grooves also provide access for grain particles to migrate out toward the grinding interface between the peripheral cast stone rings.
