Magnetic system structure for cylindrical permanent magnetic separator

Abstract

The invention discloses a magnetic system structure for a cylindrical permanent magnetic separator, which is an arc-shaped magnet combined by a plurality of primary magnetic blocks, a plurality of secondary magnetic blocks, and an plurality of auxiliary magnetic block which are in homopolar arrangement, wherein the primary magnetic blocks and the secondary magnetic blocks are arranged alternately along the axial direction of the arc-shaped magnet, the polarities of magnetic poles alternate along the axial direction of the arc-shaped magnet, the primary magnetic blocks and the auxiliary magnetic blocks are arranged alternately along the circumferential direction of the arc-shaped magnet, the polarities of magnetic poles alternate along the circumferential direction of the arc-shaped magnet, all the magnetic blocks are paired in a closely magnetic gathering way, magnetic conductive matters are stuffed among the magnetic blocks, and the primary magnetic blocks, the secondary magnetic blocks and auxiliary magnetic blocks all together form the high-field strength magnetic system structure which has a magnetic loop and, moreover, the polarities of the magnetic poles of the formed magnetic system structure alternate along circumferential and axial directions. The magnetic system structure has high magnetic field strength which is not less than 1.4T on a wider magnetic pole face (8mm); in addition, the magnetic system structure has wide strong magnetic action face, large gradient, good absorption to large granular minerals and very obvious separation effect on minerals with weak and medium magnetism.

Description

【Technical field】 [0001] The invention relates to a component of metal ore magnetic separation equipment, in particular to a magnetic system structure of a drum type permanent magnet magnetic separation machine. 【Background technique】 [0002] At present, the surface field strength of the magnetic cylinder of the domestic permanent magnetic cylinder separator can only reach a maximum of 0.9T when the pole width is less than 6mm, and the separation of weak magnetic fine ore and medium magnetic lump ore cannot achieve ideal results. Especially in the field of wet permanent magnetic drum type magnetic separator, due to the limitation of the surface field strength of the magnetic drum, the application range of the drum type machine is greatly limited, and the market urgently needs the appearance of a magnetic drum with wide pole surface and high field strength. A new type of magnetic system structure suitable for drum-type permanent magnetic separators has become a technical pro...
