Abstract: A household cereal mill is constructed wth the axis of symmetry of coaxial stationary and rotatable millstones in a horizontal alignment. The driveshaft for the rotating millstone passes through the center of the stationary millstone, and the bearing bushings supporting the driveshaft are inserted into the fixed or stationary millstone. Grain is fed into the conically expanding milling gap between the millstones from above, through a supply channel passing through the matrix of the stationary millstone at a location above the intersection of the apex of the milling gap cone and the centerline of the driveshaft. A spiral spring is employed as a conveyor worm for feed kernels, and is affixed on the outer surface of the driveshaft in a position underlying the supply passage.
