ROTOR DISC AND POLYMER MATERIAL PROCESSING DEVICE Russian patent published in 2015 - IPC B28B17/04 

FIELD: process engineering.

SUBSTANCE: invention relates to rotor disc to be incorporated with intake bin and polymer processing device. 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 transfer ribs can transfer polymer particles outward. Said ribs apply force to trapped polymer particles in direction from rotor disc centre and outward. Transfer ribs straight face and, in fact, perpendicular to lower side and lateral incident face skewed toward direction of motion or feature, in fact, triangular cross-section.

EFFECT: higher efficiency of mixing.
