ROLL GRINDER Russian patent published in 2013 - IPC B02C4/02

Abstract RU 2502562 C1

FIELD: process engineering.

SUBSTANCE: invention relates to grinding of elastomers and can be used in crushing grinders. Roll grinder comprises two rolls with horizontal and parallel rotary axes. Surface of said rolls is smooth or grooved and feature definite roughness. Said roughness exceeds equilibrium roughness for steel-rubber friction pairs of automotive tires. Roughness parameter is selected proceeding from the equation: 2R¹a≤Ra≤6R¹a, where Ra is roll surface roughness parameter, R¹a is equilibrium roll surface roughness.

EFFECT: higher efficiency of grinding.
