Abstract

A magnet device comprises a magnetic conductive layer and a magnet layer, wherein the magnet layer is attached to the surface of the magnetic conductive layer and composed of a plurality of first magnet parts and a plurality of second magnet parts; each first magnet part comprises first main magnet units and a first auxiliary magnet unit; each first main magnet unit is formed by arranging first main magnet blocks in the second direction perpendicular to the first direction, and the polarities of every two adjacent magnetic poles of the first main magnet blocks are opposite; each first auxiliary magnet unit is formed by arranging first auxiliary magnet blocks in the second direction in the mode that the polarities of every two adjacent magnetic poles of the first auxiliary magnet blocks are opposite; each second magnet part comprises second main magnet units and a second auxiliary magnet unit; the magnetization direction of the first main magnet blocks and the magnetization direction of second main magnet blocks are parallel, and the magnetization direction of the first auxiliary magnet blocks and the magnetization direction of second auxiliary magnet blocks are perpendicular to the magnetization direction of the first main magnet blocks and the magnetization direction of the second main magnet blocks; and according to the arranging sequence in the second direction, the polarities of the magnetic poles of the first main magnet blocks and the second main magnet blocks in the same serial number are opposite, and the polarities of the magnetic poles of the first auxiliary magnet blocks and the second auxiliary magnet blocks in the same serial number are opposite.

Description

technical field [0001] The invention relates to ore dressing, in particular to the field of magnetic beneficiation, in particular to a device for magnetic beneficiation. Background technique [0002] The current separation of weakly magnetic minerals using permanent magnet technology generally requires the magnetic field strength H of the magnetic pole surface 0 =480~1600kA / m or magnetic field gradient HgradH=(128~576)×10 9 A 2 / m3. Due to the limitations of the existing magnetic material preparation technology, the magnetic energy product of permanent magnetic materials is limited, and it is difficult to meet the magnetic field strength or magnetic force requirements for sorting weak magnetic minerals. Therefore, in actual production, most of them use high energy consumption and are prone to magnetic blockage , Electromagnetic magnetic separator with complex structure. [0003] There are permanent magnetic separators developed by a few companies on the market for sortin...
