ABSTRACT:
The apparatus includes a multi-compartment hopper into each compartment of which various particulated materials are fed at a grain size according to the quality of the particular layer desired in the end product, which can be in the form of a board or a animal feed cakes in strip form, and wherein the materials are continuously but controllably fed into a pressing chamber onto which a forward pressing piston operates in one preferred direction, namely the direction of the feed, and a pair of side pressing pistons act from both sides, the interaction of all pressing means forcing the pressed product into a canal at the output of the pressing chamber where it may undergo further treatment such as by heating.
