摘要

Invention Patent: B "SCREW EXTRUSION MECHANISM, IN PARTICULAR A DOUBLE SCREW EXTRUSION MECHANISM, FOR THE PROCESSING OF HIGH GAS RELEASE MATERIALS" D. A screw extrusion mechanism for processing high gas release materials comprises a main extruder (1) for the proper processing of the material, a material feed and discharge device (4,5) and a gas release device in the main extruder to discharge the gas stream from the evaporation part (14). For the branching gas stream in at least three separate streams (19,20,21), the gas release device comprises a first gas release port (13) and at least two gas release elements that are radially opposite to each other with respect to the main extruder (1) and are arranged between the evaporation part (14) and the first gas release port (13) and which are preferably designed as auxiliary screw extruders (7,8) opening radially into the main extruder.
