Abstract

The invention relates to a magnetic matrix used for a high silicon cold rolling prism-shaped rod type magnet separator, which belongs to the mineral processing equipment technical field. The invention is characterized in that the magnetic matrix is composed of two blocks of nonmagnetic metal plates and a plurality of high silicon cold rolling prism-shaped rod type magnetic conductive medium rods fixed in the nonmagnetic metal plates, two blocks of nonmagnetic metal plates are mutually parallel and embedded in a sorting space, the high silicon cold rolling prism-shaped rod type magnetic conductive medium rods are vertically fixed between two blocks of nonmagnetic metal plates to form a magnetic matrix sorting box. The high silicon cold rolling prism-shaped rod type magnetic conductive medium rods are prepared by the high silicon cold-rolled steel bar, the section is equilateral rhombus, a long pointed part of the prism-shaped rod is arranged towards to the direction of the magnetic field. The magnetic matrix used for the high silicon cold rolling prism-shaped rod type magnet separator possesses the advantages of high magnetic field gradient, large sorting space, high efficiency, energy saving, high-hardness and wear resistance, rust resistance, corrosion resistance, small retentive magnetism and the like, the better ore dressing index can be acquired, the magnetic matrix is especially suitable for recovering the weakly magnetic mineral particles with fine particle fraction.

Description

Technical field [0001] The invention relates to a magnetic gathering medium for a high-silicon cold-rolled rhombic rod type magnetic separator, which belongs to the technical field of mineral processing equipment. Background technique [0002] With the increase of resource consumption, the resources of strong magnetic iron ore and high-quality iron ore are decreasing day by day. The iron ore resources faced by the mining and metallurgy engineering steel industry are mainly hematite, limonite and siderite. The key technology to effectively recover these iron ore resources is to use a high-gradient strong magnetic separator. [0003] High-gradient strong magnetic separator is a very important mineral processing equipment in the mining and metallurgy engineering and steel industry. Its quality directly affects the utilization rate of iron ore resources, the economic benefits of the mineral processing plant, and the energy saving and emission reduction of the mineral processing ...

AI Technical Summary

Problems solved by technology

At present, the magnetic gathering medium materials of strong magnetic separators used in the mineral processing industry are mostly magnetic stainless steel and low-carbon steel surface chrome-plated materials. Although magnetic stainless steel can prevent rust and corrosion, its hardness is low and not wear-resistant. It is very low, causing high energy consumption and large residual magnetism; low-carbon steel surface chrome-plated material has low hardness and is not wear-resistant, high magnetic permeability, large residual magnetism, and short service life (because the surface chrome-plated layer is worn out. Anti-rust and loss of efficacy), but the price is low and easy to obtain
