ABSTRACT:
The movement of material being ground and/or to be ground within a grinding apparatus having opposed grinding wheels can be employed in order to promote the flow of the material to generally between the grinding wheels. A grinding apparatus to utilize such movement for this purpose has in addition to the grinding wheels a structure for causing relative rotation between the wheels, an inlet opening leading through the center of one of the wheels to generally between the wheels, and a hopper for conveying material through this opening to generally between the wheels. In addition, such an apparatus includes a shaft rotatably mounted on a bearing between the hopper and a finger or agitator extending from the shaft generally toward and preferably to within the opening in the grinding wheel, at least a portion of this finger or agitator being spaced from the axis of the shaft. As the apparatus is operated movement of the material caused by the relative rotation between the grinding wheels will cause movement of the finger or agitator so as to promote flow from the hopper to between the grinding wheels.
