Staggered magnetic plate assembly

Abstract

The invention relates to a staggered magnetic plate assembly. The staggered magnetic plate assembly comprises a concentrating flux plate arranged in the bottom, wherein magnet blocks are arranged on the concentrating flux plate, and adjacent magnet blocks in the transverse direction are arranged in a staggered manner; in the longitudinal direction, the magnet blocks comprise a first primary magnet, a first secondary magnet, a second primary magnet and a second secondary magnet arranged sequentially, wherein the pole N of the first primary magnet is upward, the pole N of the first secondary magnet faces the first primary magnet, the pole S of the second primary magnet is upward, and the pole S of the second secondary magnet faces the second primary magnet; the magnet blocks at the first andlast ends of adjacent two rows are the first primary magnet and the second primary magnet which are arranged in a cross manner, wherein the polar N of the first primary magnet is upward and the poleS of the second primary magnet is upward. According to the staggered magnetic plate assembly provided by the invention, the beneficiation yield is improved, the grade is enhanced, finer ores can be sorted, and the useable pulp density is also enhanced. Compared with existing permanent magnetic separation equipment, the use level of a magnetic material used by a neodymium iron boron group technology is reduced, and the staggered magnetic plate assembly is more economical and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of ore dressing magnets, in particular to a staggered magnetic plate assembly capable of increasing the strength of a magnetic field and improving the yield of magnetic separation. Background technique [0002] In the prior art, electromagnetic coils or large-volume high-performance permanent magnet materials are mainly used as the magnetic force source for magnetic separation. [0003] Such as: Chinese Patent Publication No.: CN105689123A, which discloses a multiple ultra-high magnetic iron ore separation device, including: magnetite sand flow, ultra-high electromagnetic coils, partitions, drains, including the formation of ore after coarse separation New ore flow; the magnetite sand flow, ultra-high electromagnetic coils, and partitions form an ultra-high magnetic iron ore separation device; the drain is composed of two partitions, which are wide at the top and narrow at the bottom. Below the ultra-high m...

Problems solved by technology

[0004] The magnetic separation method in the above technical solution consumes a lot of electric energy during the magnetic separation process of the electromagnetic coil, and the coil needs to be maintained, so the operating cost is high; moreover, the strong magnetic field cannot carry out precise screening on the mineral material, resulting in lower grade and higher impurities. many

However, the existing permanent magnet magnetic separation uses extensive permanent magnets in groups without patterned arrangement, the magnetic field is not high, and the amount of permanent magnets used is large, resulting in waste

It cannot be screened for weak magnetic or finer mineral materials, the yield is low, and the grade is not high
