FIELD: chemistry.
SUBSTANCE: invention relates to the device for material processing in pyrolytic conditions. Material is delivered from storage bin 10 to body 2 through inlet 6 and transported through body 2 with the help of extrusion screw 3. Double screw switches two screws which have opposite rotational directions and are disposed parallel to each other with positioned one-by-one blades. Blades gauge is at least half of the distance between to adjoining blades.
EFFECT: effective and fast production of processed product and good heating of material on the stage of interreaction.
