Abstract: A storage bunker for substantially dry and loose material such as shredded paper waste has a receptacle (10) and a conveyor (16,18) feeding material over a fixed plate (14) broken at (21) to permit the material to fall into the receptacle. The return run of conveyor (16) compacts material towards the other end of the receptacle, and the whole mass of material once the receptacle is filled is driven by conveyor (25) towards an outlet, with material being stripped from the mass by an inclined toothed conveyor (26) for collection by a troughed conveyor (28).

Abstract: A system for converting selected commercially or industrially derived waste materials in a generally dry and friable form, into a pelleted fuel product, comprising an input conveyor (10), a primary breaker (11) for breaking and reducing the incoming materials, a levelling drum (38), a magnetic drum (43) for extracting ferrous objects from the stream of materials, a shredder (16) from which shredded, cut and screened materials are directed by an air stream into a collecting bin (18) from which they are fed to a densifier (21) which creates a denser stream of materials to be fed to a pelleting press (22) from which the pelleted fuel product is taken via output conveyor (23).
