ABSTRACT:
A grain mill is disclosed comprising a heat-dissipating, stainless steel housing that holds a pair of grinding stones, one of which rotates with a shaft turned by an electric motor. The shaft is journaled on self-aligning bearings. The bearings and the housing cooperate to keep heat buildup from the grinding operation low so as not to damage the grain, even at higher grinding speed. As an additional check on mill temperature, a thermometer is included to provide temperature information, and an ammeter is connected to the electrical motor to provide information about the electrical current being drawn when the motor rotates the shaft as an indication of the stress on the shaft. A small door near the exit spout permits a check of the uniformity and size of the ground product. Finally, magnets on the hopper attract metal particles and hold them so that they do not enter the space between the grind stones, where they could damage the stones and become part of the product. Accordingly, the present mill is capable of higher productivity and a higher quality product. Numerous other improvements in the present mill make it easier to operate and more durable.
