Abstract
The present invention is a truck mounted mobile paper shredding system, with first and second rotary paper feed systems and a hammer mill paper shredder disposed between the feed systems. The feed systems and hammer mill are transversely mounted relative to the truck which, together with the relative positioning of the feed systems and hammer mill. provides increased paper processing speeds and a more efficient shredding operation. The invention further includes a monitoring system to prevent overfeed of the hammer mill and a low profile lift system which allows the truck to be more readily used in confined areas.

A method of providing mobile paper shredding, comprising:
- a. a first location, inputting paper to a first rotary paper feed system which advances paper to shredding equipment;
- b. positioning rotary shredding equipment below and substantially proximate said paper feed system and shredding the paper received from said first paper feed system;
- c. monitoring the shredding equipment to determine if a paper overfeed occurs, and stopping said first rotary paper feed if an overfeed of paper to the shredding equipment occurs and restarting said first rotary paper feed after the overfeed dissipate;
- d. filtering the shredded paper and allowing shredded paper which is smaller than a predetermined size to advance to a second feed system;
- e. positioning a second rotary feed system vertically below said shredding equipment, and providing said second feed system with a plurality of circumferentially staggered blades to advance the shredded paper to a storage area;
- f. storing the shredded paper in the storage area;
- g. at a second location, removing the shredded paper from said storage area.
