DEVICE FOR PROCESSING POLYMER MATERIAL Russian patent published in 2016 - IPC B29B13/10 

FIELD: technological processes.

SUBSTANCE: invention relates to a device for preliminary treatment and further transportation or plastification of polymers. Proposed device for preliminary treatment and further transportation or plastification of polymers, which comprises hopper with mixing and/or grinding tool installed in it with possibility of rotation around the axis. At that, in hopper side wall there is hole, through which polymer material is unloaded, and there is multi-screw conveyor with at least two screws rotating in housing. At that, supposed continuation of conveyor longitudinal axis passes opposite to transportation direction past axis of rotation. At that, longitudinal axis of screw nearest to hopper at outlet side is displaced by distance from parallel longitudinal axis of radial, and both screws nearest to feeding hole are made with opposite action to each other.

EFFECT: higher efficiency and quality of processing sensitive and strip-like materials.
