Abstract: Prior to entering a tumbling media mill grinding chamber, feed containing clumps of adherent fine and coarse particles is brought into jarring contact with a moving member for liberating fine particles. Liberated fines are contacted, outside the chamber, with a current of gas to remove them from the remainder of the feed. At least a portion of this remainder enters a bed of charge material in the chamber and is ground with the media. When an indicator of a developing or existing over-fed or under-fed condition in the bed is sensed, adjustment of the jarring intensity, of the gas velocity or of both is made in response to the indicator for increasing and decreasing the quantity of fine particles removed from the feed. A clump separator, having an enclosure, jarring member and coarse solids outlet, may be used to liberate fines. This outlet is connected with a coarse solids inlet to the chamber. A path other than the coarse solids outlet is provided for removing liberated fine particles from the enclosure.

Abstract: A self-cleaning garbage disposal utilizes a spray ring which is located below the splash guard. A control valve is connected to the cold water pipe and controls the flow of water from the cold water line into the spray ring. The control valve is engaged simultaneously with the disposal when the disposal is activated, which also initiates a timer control circuit on the control valve. The spray ring, using standard water pressure, forces the food debris directly into the disposal blades in a counterclockwise direction for faster and more efficient grinding of the food debris. When the disposal is switched off, water continues to flow through the spray ring for approximately fifteen seconds, thoroughly flushing any remaining debris down the drain.
