Permanent magnet vibration module type magnetic separator

Abstract

The invention relates to a permanent magnet vibration module type magnetic separator, which is characterized by comprising a stand (2) and a sorting unit installed above the stand (2) through a vibration mechanism. The sorting unit comprises a sorting cavity (13), a feeding hole (11) positioned at the top of the sorting cavity, a discharge hole (20) positioned at the bottom part of the sorting cavity, and at least one magnetic matrix box (21) which is coaxial with the sorting cavity, is arranged in the sorting cavity and vertically extends downwards to the discharge hole, wherein the two sides of the magnetic matrix box (21) are respectively provided with a pair of permanent magnetic steel (10) which can make coaxial and relative horizontal displacement motion.

Description

Technical field [0001] The invention belongs to the technical field of beneficiation, and relates to a separation device for magnetic particles and non-magnetic particles in fine-grained materials, in particular to a permanent magnet vibration modular magnetic separator, which is convenient for large-scale equipment and can be used for coal burning Desulfurization, impurity removal and purification of non-metallic minerals, etc. Background technique [0002] At present, most of the existing permanent magnet magnetic separators have a single arrangement of magnetic systems. The magnetic circuit design is complicated and the magnetic induction intensity generated is generally low. It is only suitable for the selection of ferromagnetic iron ore, and it is difficult to select low-grade iron ore. Stone and weakly magnetic iron ore are selected. At the same time, the selection of permanent magnet magnetic separator equipment is too complicated and takes up too much space; in some appl...

Problems solved by technology

However, since the former is "powder separation in the air gap magnetic field channel", the latter is through "the inner cylinder swings to separate the magnetic and non-magnetic substances", which will inevitably lead to their structural complexity and operational complexity. Complicated, thus affecting the promotion and application

[0006] However, for the magnetic separation of weak magnetic minerals such as manganese ore and hematite, electromagnetic induction roller-type strong magnetic separators are mostly used. Electromagnetic magnetic separators have problems such as high power consumption, easy blockage, and high cost; for current magnetic separation In the case of many and complicated applications of machines, it is imminent to find a permanent magnet magnetic separation equipment suitable for removing iron and impurities from non-metallic ore solid waste, which is low in cost, high in separation accuracy, large in processing capacity, and not easy to clog.
