Patent ID: 10821645

Abstract:
The devices relate to the nuclear, metallurgical, mining, machine-building and food industries and may be used in producing semi-finished products and items made via the extrusion of powders of composite, polymer and other plastic masses. A device for producing semi-finished products or items made of composite, or polymer, or plasticized powder materials includes a screw press with a housing and a screw within the housing. The housing and the screw each have at least one deformational portion with protrusions and may each be formed integrally with the protrusions or may be formed compositionally, having special insertable rings which are provided with protrusions. In carrying out all three device variants, the housing and the screw are formed compositionally, and have provided, on the deformational portions of a ring, stators, which are secured to neighboring portions of the housing, and rotors, which are secured to neighboring portions of the screw.
