DEVICE TO SIZE FEATHER-AND-LINT STOCK IN FLUID Russian patent published in 2012 - IPC B68G3/08 B07B1/20 D01B3/00 

FIELD: process engineering.

SUBSTANCE: proposed device comprises tank divided by web, mixing cylinder with bar to rotate two-phase fluid with sizing assemblies arranged on cylinder sides. Said sizing assemblies comprises shields and guide chambers to size raw stock, accumulation bins fro separate sized fractions from fluid, pressure pump to circulate fluid, system of pipelines, shutoff and control valves. Between tank side wall and shutoff and control valve arranged is chamber for modification incorporating two rolls. One roll represents a modifying roll with spur, helical or chevron incisions. Another roll is a pressure roll elastic coating. Or both have spur, helical or chevron incisions. It comprises also guide screen composed of taper channel with perforated end.

EFFECT: higher efficiency of separation and quality of feather fractions.
