MAGNETIC SYSTEM Russian patent published in 2007 - IPC B03C1/25 

FIELD: chemical industry; mining industry; alimentary industry; glass industry; other industries; production of the magnetic systems for the magnetic separators.

SUBSTANCE: the invention presents the magnetic system, which is intended for dressing of the low-magnetic concentrates of the different type in mining, alimentary, glass, chemical and other industries. The invention allows to increase efficiency of separation by usage of the magnetic system with the optimally selected ratio of dimensions of the magnetic system components directly influencing on the magnetic force of the magnetic field and the gradient of the magnetic field intensity. The magnetic system includes the block of the permanent disk-type magnets with the disk magnetic concentrators interleaved with them one after another rigidly mounted on the horizontal shaft. The butt planes of the permanent disk magnets and the disk magnetic concentrators are perpendicular to the horizontal shaft of the system. The permanent disk magnetic are made out of the alloys of the rare-earth metals on the basis of Nd-Fe-B or Sm-Co, are facing each other with the similar poles and are limited by the end washers. Parameters of the components of the magnetic system effecting on the magnetic force of the magnetic field and the gradient of the magnetic field intensity are coupled among themselves by a following ratio: L = n(b_m+b_k)-b_k+2b_t, where L is the length of the magnetic system;_{bm is the depth of the disk magnet; bk is the depth of the disk concentrator;bt is the depth of the end washer; n is the quantity of the disk magnets.}

EFFECT: the invention ensures the increased efficiency of separation due to usage of the magnetic system with the optimally selected ratio of dimensions of the magnetic system components directly influencing on the magnetic force of the magnetic field and the gradient of the magnetic field intensity.
