Abstract

A screw press has a screw (2) with a land (3) thereon and is rotatable in a cylinder (1). Pegs (4) project inwardly from the wall of the cylinder (1) towards the axis of the screw and pass through a circumferentially extending passage in the land (3). End surfaces (10, 11) of the land formed by the passage therein face one another and are directly opposite one another when considered in a direction axially of the screw thereby to constrain material being processed to pass through narrow gaps between the peg (3) and the end surfaces (10, 11) of the land with consequent introduction of shear forces into the material to improve its homogeneity. The screw (2) may be a multi- start screw or short lengths of multi-start lands may be provided immediately upstream and down- stream of the position at which a plurality of the pegs (4), located in a plane normal to the axis of the screw (2), are disposed, i.e. on either side of the passage. <IMAGE>
