The processing housing incorporates a feed or delivery point. There are pressure pipes and a cutting section housing (3) which is split. The split ensures that the feed or delivery point alone, or this and a part of the pressure pipe, or the feed or delivery point and the whole pressure pipe, are located in a new construction known as the delivery block (4). The delivery block accommodates the processing screw. It is located so as to rotate to be torsion-free in an overall housing (6).
