Abstract
A shredder including a shredder housing having an inside, an outside, side walls, end walls, such that the end walls and side walls are engineered and joined together to maintain tight tolerance within the shredder. The end walls and side walls define a top inlet opening and a bottom outlet opening. Two parallel spaced apart shafts are horizontally aligned with each other and rotationally mounted through the end walls for receiving rotational power. Adjustable speed rotational motors engage each of the shafts for rotating them in counter-rotational directions. A plurality of uniform thickness disk-shaped blades are alternatingly positioned with interposed disk-shaped spacers placed therebetween. The spacers have a thickness slightly thicker than the blades. The blades and spacers are arranged on the shafts and mounted for counter-rotation with the shafts in an interdigitated fashion so that the blades on one of the shafts are aligned with the spacers on the other shaft such that the blades pass side-by-side closely spaced with the blades on the counter-rotating shafts so that close tolerance cutting occurs between the blades.
