ROTOR DISC AND POLYMER MATERIAL PROCESSING DEVICE Russian patent published in 2015 - IPC B01F7/00 

FIELD: process engineering.

SUBSTANCE: rotor disc is to be fitted in intake bin for processing of polymers by disc body. Disc body top side has mixing and/or grinding working members while some transfer ribs are made at opposite bottom side to extend from inside to outside. Said ribs displace polymer particles outside or bring force to polymer particles caught by said ribs directed from rotor disc centre outward. Said transfer ribs are concaved in direction of displacement.

EFFECT: efficient prevention of ingress of polymer particles in between disc and intake bin bottom or their removal from said area.
