A grinding mechanism or assembly for a food waste disposer, the grinding mechanism being enclosed in a housing of the food waste disposer. The grinding mechanism includes a shredder plate assembly and a stationary shredder ring. The shredder plate assembly has an upper rotating plate and a lower lug support plate. The lower lug support plate has a body portion, and shredder lugs and tumbling spikes integrally formed with the body portion. The upper rotating plate has key slots and key holes for receiving the fixed shredder lugs and tumbling spikes. The stationary shredder ring is fixed to the housing of the food waste disposer and has a plurality of teeth. The stationary shredder ring may also have diverters and breakers. The fixed shredder lugs force food waste against the teeth of the stationary shredder ring to grind the food waste into particulate matter. The profile of the fixed shredder lug may include a vertical toe, a notch and a heel.
