Food waste disposer grinding mechanism
A grinding mechanism for a food waste disposer includes a grinding ring defining a plurality of window openings therethrough. A backing member receives the grinding ring and defines a plurality of cavities therein corresponding to the window openings. A plurality of stacked disks form a rotatable shredder plate that is situated to rotate relative to the grinding plate.
