CENTRIFUGAL DRUM SEPARATOR Russian patent published in 2011 - IPC B07B9/00 

FIELD: process engineering.

SUBSTANCE: invention relates to separators intended for separation of, mainly, cereals, by fractions, and may be used in agriculture for selection of cereals, and etc. Proposed separator comprises at least one centrifugal vibrating cylindrical drum with screens and vertical shaft, and grain distributor arranged above said drum. Drum vertical shaft represents a crankshaft to generate drum radial oscillations for transfer of material being separated along tear-off trajectory relative to screen inner surface. Rocker made up of counterweight is fitted on drum shaft inside said drum to move and be locked in several directions. Cylindrical drum is made up of two semicylinders with their joint edges representing right-angle zigzag. Note here that drum screen joint is provided with stiffness ribs and device to force screen joint edges toward said stiffness ribs.

EFFECT: higher quality and efficiency of separation and longer life.
