Magnetic separator for efficiently separating magnetic materials

Abstract

The invention provides a magnetic separator for efficiently separating magnetic materials. The magnetic separator comprises a box, a rotating drum arranged on the box, a magnetic component which is arranged in the rotating drum and does not rotate with the rotating drum, a feed port which is arranged on the box and located above the rotating drum and a discharge port which is located below the rotating drum. The magnetic separator is characterized in that the magnetic component comprises a fixed roller, axial magnetic conducting stripes which are arranged at intervals on the surface of the fixed roller, and permanent magnets of which each is arranged between the two axial magnetic conducting stripes, wherein the magnetic poles of the permanent magnets are arranged in the same polar direction on both sides of the axial magnetic conducting stripes so that the magnetic materials can be separated more easily, and the problems that the magnetic separation effect and the recovery rate are difficult to improve due to the magnetic clamp and the mechanical inclusion can be completely solved, the magnetic separation efficiency is high, the magnetic separation is thorough and environment protection and energy conservation are realized. The concentrate with the metal grade of more than 66% and the metal recovery rate of more than 85% can be obtained by only using the magnetic separator.

Description

technical field [0001] The invention relates to a magnetic separator, in particular to a magnetic separator for efficiently separating magnetic substances, and belongs to the technical field of magnetic separation equipment design and manufacture. Background technique [0002] Magnetic separators are widely used in industrial production, especially in the mineral processing industry, and are used to separate magnetic minerals such as manganese ore, magnetite, pyrrhotite, ilmenite, and hematite. It can also purify and reduce impurities of non-metallic minerals such as quartz sand and feldspar. The existing magnetic separator consists of a box body, a drum that is driven by a drive assembly to rotate and is supported by the box body, a magnetic assembly that is arranged in the drum and does not rotate with the drum, a material inlet that is arranged above the box body, and a material outlet that is below the box body. mouth. In the process of separation and magnetic separati...

AI Technical Summary

Problems solved by technology

In the process of separation and magnetic separation, due to the unreasonable setting of the magnetic components, mechanical inclusions will be generated to carry non-magnetic substances into the concentrate, and secondly, a small amount of non-magnetic substances contaminated with magnetic substances will be carried due to the entrainment effect of the magnetic components. Into the concentrate, resulting in unsatisfactory separation of magnetic materials and non-magnetic materials
