MULTICHAMBER MAGNETIC SEPARATOR WITH TRAVELLING MAGNETIC FIELD Russian patent published in 2011 - IPC B03C1/00 

FIELD: process engineering.

SUBSTANCE: invention relates to dressing of mineral resources. Proposed magnetic separator comprises magnetic system arranged on both sides of separation chambers and made up of magnetic units with alternating magnetic polarity or of alternating single and twin magnetic units wherein magnetic polarity of single units is opposite that of twin magnetic units. Magnetic units are arranged between nonmagnetic plates along disk circumference of 360° at a distance between units smaller than their width. If magnetic system has alternating magnetic polarity, then units arranged on one line and on both sides of separation chamber feature codirectional vectors of magnetic induction. If magnetic system is made up of alternating single and twin magnetic units, then those on both sides of separation chambers are displaced along the circumference through the angle that allows single units to stay on line crossing the twin units division center and to have codirectional vectors of magnetic induction.

EFFECT: higher intensity of travelling magnetic field in separation zone, reduced costs and higher specific efficiency.
