Parallel magnetic plate assembly

Abstract

The invention relates to a parallel magnetic plate assembly. The parallel magnetic plate assembly comprises a magnetic conductive plate arranged at the bottom. Parallel magnetic strips which are composed of magnetic blocks and arranged longitudinally are arranged on the magnetic conductive plate. All the parallel magnetic strips are provided with the magnetic blocks with the same sequence and sametype in the longitudinal direction. A first main magnet with the N pole facing upwards, a first secondary magnet with the N pole facing the first main magnet, a second main magnet with the S pole facing upwards and a second secondary magnet with the S pole facing the second main magnet are sequentially arranged in the longitudinal direction of each magnetic strip; and every the four magnets forma component unit of the magnetic strips. Each of the parallel magnetic strips comprises at least one set of the component unit. All the component units are arranged in sequence. The first main magnetwith the N pole facing upwards is arranged at the last end of each of the parallel magnetic strips. The beneficiation yield is increased, the grade is improved, finer minerals can be separated, and the concentration of ore pulp which can be used is increased; and the magnet consumption is reduced through a neodymium iron boron group technology, and the parallel magnetic plate assembly is more economical and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of ore dressing magnets, in particular to a parallel 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 ma...

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
