ABSTRACT:
A mill for grinding vegetable products comprises a fixed upper annular millstone in engagement with a lower rotatable millstone. The upper annular millstone has a central opening through which vegetable products such as grains are fed. Fixed to and extending axially upwardly from the lower millstone is a screw that extends in spaced relation through the central opening of the upper millstone and is threaded in a direction such that upon rotation of the lower millstone, the screw turns in such a direction as to serve as a screw conveyor to move material upwardly. In this way, the screw acts to unblock the passageway and prevent the bridging over of material such as might clog the mill. The screw terminates upwardly in a cutaway portion that provides an agitator offset to one side of the lower portion of the screw; and this offset portion serves as a stirrer to prevent clogging.
