Abstract

A portable flour mill includes a fixed grinding wheel and a rotatable grinding wheel located inside a box-like housing. The fixed grinding wheel has a smooth and a tapered portion on its grinding face and is fastened to a removable interior wall of the housing. The rotatable grinding wheel has five symmetrically arranged V-shaped radial grooves on its grinding face and is journaled for rotation in a fixed interior wall opposite the fixed grinding wheel. The fixed grinding wheel is provided with an entranceway for receiving the grain which is to be ground. A feed hopper rests on a plate fixed to the removable interior wall and includes an exitway coincident with the entranceway of the fixed wheel. The wheels are selectively spaced apart with each other to grind different types of grain. Means for adjusting the spacing between the two wheels are disclosed.
