ABSTRACT:
A household grain mill includes a mill in which the grinding surfaces of the millstones (18, 20) are provided with recesses (28) which extend from the inside toward the outside with decreasing depth and which crack grain fed through a central opening and lead it to an outer grinding zone. The recesses (28) have an asymmetrical cross-sectional shape with two flanks (34, 36), of which the leading flank (34) is steeper than the trailing flank (36) and, together with the flatter flank (36) of the preceeding recess (28), forms an edge (38) which runs tangentially to the periphery of the central opening.
