Problems solved by technology

[0002] Traditional wet magnetic separators have been gradually replaced by dry magnetic separators due to the large investment in equipment, serious environmental pollution, harsh working environment, astonishing waste of energy consumption, land and water resources, etc.
At present, the dry magnetic separators developed in China are basically of drum structure. In order to improve work efficiency and magnetic separation effect, the structural design of the machine itself is relatively complicated and occupies a large area. Once the machine fails, it is very difficult to maintain
Not only that, there is still a gap in quality between the minerals produced by the existing dry magnetic separation equipment and the products of the wet process

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 As shown, the present invention provides a rotary dry magnetic separator. Its structure includes a superconducting magnet 1 with divergent magnetic force lines and a sorting structure; the superconducting magnet 1 forms divergent magnetic force lines at two ends, and a multi-layer flat plate (separation disk) that can penetrate the magnetic force lines is arranged at the two end faces; the separation The selection structure includes at least one rotatable sorting disc 2 and a scraper group ( figure 1 not shown in ); the magnetic field lines of the superconducting magnet 1-magnetic end face pass through the sorting disc 2; the sorting disc 2 and the scraper group are both made of non-magnetic materials. Due to the divergence of the magnetic force lines of the superconducting magnet 1, the magnetic hair needles formed when the ma...

Abstract

The invention provides a rotary dry type magnetic sorting machine. The rotary dry type magnetic sorting machine comprises a superconducting magnet with dispersed magnetic force lines, and a sorting structure, wherein the sorting structure comprises at least one sorting disc and a scraper plate set matched with the sorting disc; the magnetic force lines of the superconducting magnet penetrate through the sorting disc; and the sorting disc and the scraper plate set are made of non-magnetic materials. The rotary dry type magnetic sorting machine disclosed by the invention is simple in structure and the dispersed magnetic force lines of the superconducting magnet penetrate through the sorting disc, so that the sorting disc and the superconducting magnet can be separately arranged; and not only can the fault rate of a machine be effectively reduced, but also the sorting disc can be conveniently and vertically arranged when being overhauled and replaced, so that the gravity effect in a sorting process can be sufficiently utilized and a lot of energy sources do not need to be additionally consumed.

Description

technical field [0001] The invention belongs to the field of mineral separation, in particular to a rotary dry magnetic separator suitable for large-flow dry powder ore. Background technique [0002] Traditional wet magnetic separators have been gradually replaced by dry magnetic separators due to the large investment in equipment, serious environmental pollution, harsh working environment, and astonishing waste of energy consumption, land and water resources. At present, the dry magnetic separators developed in China are basically of drum structure. In order to improve the work efficiency and magnetic separation effect, the structure design of the machine itself is relatively complicated and occupies a large area. Once the machine fails, it is very difficult to maintain. Not only that, but there is still a gap in quality between the minerals produced by the existing dry magnetic separation equipment and the products of the wet process. It is mainly manifested in that when ...
