ABSTRACT:
A motor-driven nut-grinding apparatus is constructed to effectively operate at much lower than conventional speeds and has a front-mounted, unitary casting part providing a back mounting plate wall, a feed chute, a forwardly extending feed and grinding hub, and a front mounting for a stationary grinding disc. The hub has an open-end bore that journals a motor-driven auger shaft on which a rotating grinding disc is mounted to cooperate and define a final grinding chamber with the stationary grinding plate. A back portion of the auger shaft has a cylindrical, reduced diameter portion that with at least about one and a half of auger convolution turns, is exposed through a window in the hub and an open mouth of the chute to provide a non-jamming receiving area for nut kernels from a downwardly converging mouth portion of the feed chute. The length of the cylindrical portion is sufficient to freely receive nuts or kernels lengthwise thereon for non-interrupted feed delivery of a full charge of nut material to worm convolutions of the auger shaft. The hub and auger shaft provide a preliminary or rough grinding action and the pair of grinding discs provide a final, fine grinding action on the nut material.
