METHOD OF MAGNETIC SEPARATION OF FLUID OR DUS-GAS PRODUCTS AND MAGNETIC SEPARATOR TO THIS END Russian patent published in 2012 - IPC B03C1/00 

FIELD: process engineering.

SUBSTANCE: proposed method relates to magnetic separation of fluid or dust-gas products with fine low-magnetic admixtures and may be used in ceramics, power engineering, pharmaceutics, mining, etc. Proposed method comprises passing the product to be separated through array filter 5 fitted in case 4 and made from ball-shaped ferromagnetic granules located in magnetic field of magnetic system 6 made up of permanent magnets, depositing product magnetic fraction particles on array filter granules, terminating magnetic field effect by moving array filter filled with sediment from magnetic field, breaking the structure of array filter and contacts between adjacent granules by mechanical means, cleaning filter of deposited product particles by rinsing with water or blowing by compressed air. Aforesaid moving from magnetic field, removing contacts between granules and cleaning granule surfaces of deposits are carried out by centrifugal forces brought about by tapered flow case arranged vertically and having its side surface at acute angle to vertical.

EFFECT: simplified design, optimised magnetic filter, higher efficiency of separation.
