2123800 9310893 PCTABS00022 Disintegrated material is supplied by means of a reciprocating scew piston (2) into a pressure chamber. By rotation said piston in a first axial position is transporting and compacting the material in a receiving chamber (5) against an output valve (4) in front of the piston. The output valve is opened and said compacted material is moved into the pressure chamber by axial non rotative motion of the piston. The output valve then is closed and the piston is axially returned to its first axial position while rotating in the same direction as before. The operation cycle is repeated as above. An apparatus for carrying out said process comprises an axially movable guide piston (7) rotationally carrying and guiding the screw piston (2) for rotation and axial movement by action of a hydraulic cylinder (11) and a mechanism (12) for rotationally positioning the screw piston.
