DEVICE USED FOR PREPARATION OT THE POLYMERIC MATERIAL FOR THE RECYCLING Russian patent published in 2007 - IPC B29B13/10 B29C47/10 

FIELD: chemical industry; devices for preparation of the polymeric material, predominantly thermoplastic, to its recycling.

SUBSTANCE: the invention is pertaining to the device for preparation of the polymeric material, predominantly thermoplastic, to its recycling. The device contains the tank, in which there is at least one gyrating mixing and-or mincing tool. At that the treated material is routed to the disposed in the tank bottom discharge outlet, with which the body feeding inlet is streamwise connected. The device contains at least two feed screws fed together. The invention also presents the dependence between the diameters of the tank and the diameters of each of the feed screws with usage of the constant value, which exceeds or is equal to 50. The technical result of the invention is the possibility providing the more uniform feeding of the material subjected to the recycling into the device adjoining to the discharge outlet, and the uniform outlet of the agglomerate on the discharge end of the feed screw. The design pertaining to the geometry of the feed screws is less sensitive to reprocessing of the various polymers.

EFFECT: the invention ensures the possibility providing the more uniform feeding of the material subjected to the recycling into the device adjoining to the discharge outlet, and the uniform outlet of the agglomerate on the discharge end of the feed screw and the low sensitivity of the device design reprocessing of the various polymers.
