HORIZONTAL ELASTIC CENTRIFUGE Russian patent published in 2012 - IPC B04B3/00 B04B5/12 B04B11/04 

FIELD: process engineering.

SUBSTANCE: invention relates to mining, concentration of minerals and may be used for dehydration of fines. Horizontal centrifuge comprises perforated rotor, housing, frame electric drive, initial pulp feed pipeline, centrate discharge pipeline and dehydrated material discharge trough. Centrifuge rotor features shape similar to that of automotive tire with open cavity on one side and tight wall on opposite side. Said rotor is made from resin and has multiple 3 mm-dia holes. It is has its outer edges reinforced by steel wire to prevent rotor blowout. Filter screen with tiny holes is secured inside said rotor. Dehydrated material is discharged in cycles when squeeze roller presses against rubber rotor outer surface to create bulge in rotor inner surface and opposite-direction centrifugal force is created.

EFFECT: higher yield, reduced losses, possibility to use centrate as circulation water.
