A dual shredding system for a mobile document shredding vehicle produces either coarsely shredded material or finely shredded material. Unshredded material is first coarsely shredded by a coarse shredder. In a coarse shred mode, the coarsely shredded material is routed to a shredded material storage compartment in the vehicle. In a fine shred mode, the coarsely shredded material is finely shredded by a fine shredder, and then routed to the storage compartment. The position of a gate determines whether the system is in the coarse or fine shred mode.

Dual shredding system for a mobile document shredding vehicle and method of use

A mobile shredding system is used mounted on a vehicle. The system has a hopper, for receiving material to be shredded, a shredder communicating with the hopper, and a holding space for shredded waste into which the shredder feeds shredded material. A bin lifting mechanism with at least one chain onto which a carriage is attached is mounted on a side of the vehicle. The carriage has an engagement mechanism for attaching a bin and the chain is movable by means of a drive mechanism from a lowered position, in which the carriage is adjacent the ground on which the vehicle is standing, and a raised position, in which the carriage is adjacent an inlet of the hopper and the contents of the bin are emptied into the hopper via the inlet. The carriage has a weight measuring mechanism such as a load cell incorporated therein to measure the weight of the bin when the bin is attached to the engagement mechanism. The system further has a weight indicating display, and also a electronic storage of the measured bin weight.

Rows of finger blocks are mounted to a frame body of a rotary industrial shredder laterally parallel to respective ones of the counter-rotational pair of shafts so as to be moveable slightly, but meaningfully, during the shredding operation while maintaining tight clearance relationships between the fingers and cutters. In such a manner, waste material, particularly waste fibrous material such as waste carpet, may be stripped satisfactorily from the cutter and spacer discs carried by the shafts. Preferably, the finger blocks include unitary cutter and spacer fingers extending inwardly towards the shafts in respective opposed relationship to cutter and spacer discs carried thereby.
