METHOD FOR MAGNETIC SEPARATION AND MAGNETIC SEPARATOR FOR ITS REALISATION Russian patent published in 2008 - IPC B03C1/10 

FIELD: technological processes; physics.

SUBSTANCE: method of magnetic separation includes performance of separation at the speed of separated medium in slot channel that corresponds to circumferential speed of every one of drums that rotate towards each other, subsequent removal of retained deposit of magnet-sensitive fraction from surface of drums after drain of medium that went through separation from working zones. Drain of this medium is carried out in undisturbed mode on the section of tail working zone between shortened branch of saddle-type channel and edge of magnetic sector. Magnetic separator consists of two rotary drums, inside of which magnetic sectors are installed that are turned to each other and saddle-type channel with two symmetrical branches installed under drums. One receiving and two tail working zones of medium separation are created between magnetic sectors. Branches of saddle-type channel are arranged as impermeable and shortened compared to tail work zones, every of which is limited with edge of magnetic sector. Beyond borders of every magnetic sector, along direction of drum rotation, combined device is installed for removal of deposit of magnet-sensitive fraction from drum surface.

EFFECT: higher efficiency of magnet separation process.
