Abstract

A material processing plant comprises a first screw-type extruding machine (1) and a second screw-type extruding machine (2) which is disposed downstream thereof. Between the two screw-type extruding machines (1, 2), provision is made for a delivery zone (28) where a delivery orifice is provided, extending radially of the axes (12a, 13a) of the casing bores (12, 13) of the first screw-type extruding machine (1) and being directed towards the second screw-type extruding machine (2). The at least one casing bore (12, 13) of the first screw-type extruding machine (1) is lockable in the direction of its axis (12a, 13a) by means of a sealing element.
