METHOD OF RAW RUBBER GRINDING FOR RUBBER-BASED COMPOSITIONS Russian patent published in 2014 - IPC B02C18/06 C08J11/00 C08J3/20 

Abstract RU 2508945 C2

FIELD: process engineering.

SUBSTANCE: invention relates to raw-rubber grinding, introducing it to polypropylene polymer composition to up its adhesion to lacquer coating and to increase impact characteristics for moulded articles. Rubber pellets are cut by air-driven knives and ground by the device composed of forced-cooled cylinder, screw and rotary knives arranged at screw outlet.

EFFECT: fine rubber flakes sized to 0,2-3 mm and having loose structure.
