SUBSTANCE: mixer-doser of a press extruder contains a hopper (mixing tank), at the lower part of which a feeding screw is fixed. The feeding screw body with its free end is fixed to the chamber of the press extruder. In the hopper (mixing tank), trapezoidal curvilinear blades are fixed on the drive shaft, facing with their concaves towards the rotation direction. Transversal bars are installed on the feeding screw, and slits are made in the screw flight to ensure the multiple change in the direction of the conveying material, which improves its mixing.

EFFECT: use of the invention will allow to improve the quality of mixing the mixture components and to stabilise the extrusion process due to feeding the material into the cylinder of a press extruder under pressure.
