FIELD: process engineering.
SUBSTANCE: invention relates to equipment intended for extrusion of stock comprising several components to be used in processing branches. Extruder consists of a cylinder with loading opening, vaned screw arranged in said cylinder and outlet female die. At least, one compression gate is rigidly secured on said screw. Said gate features stepped shape with ribs for separation of materials forced toward compression gate in separate flows and for enlargement of the area of contact with the gate.
EFFECT: higher efficiency and quality.
