TAPELESS ROLLER-TYPE MAGNETIC SEPARATOR Russian patent published in 2010 - IPC B03C1/10 

FIELD: process engineering.

SUBSTANCE: invention relates to magnetic separation equipment. Proposed magnetic separator comprises rotary magnetic roller. Its magnetic system consists of circular or disk-like permanent magnets, magnetised axially and separated by circular or disk-like ferromagnetic concentrators. Adjacent permanent magnets adjoin thereto by like poles. Separator comprises also cleaning device arranged along magnetic roller to clean roller working surface of magnetic particles of separated product, feeders, separators and receivers of separated product. Said cleaning device represents solid ferromagnetic drag-type body with ledges sharpened towards roller surface. Magnetic flows of the roller system of permanent magnets are closed along the roller via said ledges to generate magnetic fields acting along roller axis. Said fields are directed from roller working surface towards ferromagnetic body sharpened ledges.

EFFECT: simplified process, lower costs.
