Moving magnetic pole permanent magnet separator

Abstract

The invention relates to a moving magnetic pole permanent magnet separator which comprises a separation cavity, an ore feeding pipe, a water supplementing pipe, an overflow groove, a tailing pipe, a concentrate pipe, N layers of magnetic systems, a magnetic system support and a linear motor; the separator is characterized in that the separation cavity is a box body with an open upper part and a cone lower part, the overflow groove is fixedly connected to the periphery of the upper part of the open box body, and the bottom of the lower end of the overflow groove is connected with the tailing pipe; the bottom of the cone is connected with the concentrate pipe, the ore feeding pipe is arranged at the middle-upper part of the open box body, and the water supplementing pipe is arranged at the lower part of the open box body; the N layers of magnetic systems are arranged on the two sides of the outer portion of the separation cavity, the N layers of magnetic systems on the two sides of the outer portion of the separation cavity are arranged in a staggered mode from top to bottom, N is larger than or equal to 2, each layer of magnetic system is fixedly connected with a correspondingly-arranged magnetic system support, idler wheels are arranged at the bottom of the magnetic system support, and the magnetic system support is connected with a linear motor shaft capable of achieving reciprocating motion. The separator has the advantages that the structure is simple, the cost is low, the investment is small, concentrate descends along the Z-shaped path, and magnetic inclusions are few.

Description

technical field [0001] The invention belongs to the technical field of magnetic separation equipment, and in particular relates to a moving magnetic pole permanent magnet magnetic separator with simple structure and low manufacturing cost. Background technique [0002] Permanent magnetic drum magnetic separator and magnetic separation column have been widely used in magnetite ore dressing plants, and are the main equipment of magnetic separation plants. The permanent magnet drum magnetic separator can be used for roughing and beneficiation operations. The magnetic separation column is a beneficiation equipment and can only be used for beneficiation operations. The permanent magnet drum type magnetic separator adopts a fixed permanent magnet system, and the rotating permanent magnet cylinder is concentrically set on the outer surface of the permanent magnet system. The magnetic particles in the pulp are adsorbed to the outer surface of the permanent magnet cylinder under the ...

AI Technical Summary

Problems solved by technology

Magnetic separation column equipment also has the problems of complex equipment structure, high cost, prone to failure of electromagnetic conversion and control mechanism, and high energy consumption

In addition, the permanent magnet drum type magnetic separator and the magnetic separation column equipment have different degrees of magnetic inclusion problems in the separation process, and the magnetic inclusion problem of the permanent magnet drum type magnetic separator is more serious, which affects the improvement of the concentrate grade.
