The purpose of the invention is to increase productivity due to the quick installation of the device and ease of maintenance. . The objective is achieved by the fact that in a mixing device for plastics, mainly thermoplastics, comprising a housing with inlet and outlet openings, there is a mixing rotor therein associated with a drive for its rotation and a throttle element, spaced in the area of the outlet opening, according to invention, the throttle element is a complete 8-type cylindrical sleeve with a radial bore channel, which surrounds the mixing rotor and is concentric, with the outlet of the housing located but relative to the axis of the mixing rotor, the mixing device is equipped with an outlet fitting with a passage through the CM channel placed in the area of the outlet with the possibility of blocking its flow channel with a cylindrical sleeve. FIG. 1 shows a mixing device, FIG. 2 is a section A-A of FIG. 1. The mixing device comprises a housing 1 with an inlet (not shown) and 2 outlet openings, a mixing rotor 3 spaced therein, associated with drive A of its rotation. The mixing rotor 3 will be screwing the shaft installed on both sides into the supports with parts of the auger and kneading discs mounted in any sequence. At its end, the mixing rotor 3 is connected to the return screw 5.
