Abstract

A process and an apparatus for the production of paper products, such as 'cat litter' or paper fuel, comprising reducing paper to a particulate form by shredding and grinding, conveying the particles of paper from a hopper as a layer on a first conveyor firstly beneath a leveling and compacting roller and thereafter beneath a set of water sprayers, before discharging from the conveyor onto a second conveyor with the assistance of a rearwardly baffle plate to invert the layer during transfer. The inverted layer on the second conveyor passes to a third conveyor belt which moves through a ring with has the effect of wrapping the belt over itself and around the mix to form a tunnel enveloping and compacting the mix to form an extrusion. The paper product as extruded is cut into pellets before subjecting the pellets to dehydration. In the case of paper product to be used as paper fuel, the paper is mixed with coal dust. The bottom of the hopper contains a plurality of rotatable worm screws for discharging the paper evenly across the conveyor while rotatable paddle agitators are also contained in the bottom of the conveyor to prevent the particulate paper from agglomerating into lumps.
