Permanent magnetic classificator

Abstract

The invention discloses a permanent magnetic classificator. The permanent magnetic classificator comprises a main frame, a power frame, a coupler, a speed reducer, a motor, a bearing pedestal, a support seat and a magnetic system adjustment device, also comprises a magnetic cylinder device composed of a magnetic cylinder, a seal cover, a magnetic system, a magnetic system shaft and helical blades, and also comprises a feeding device, an ore washing tank, an ore unloading plate, an ore discharge tank, a concentrate unloading hopper, a tailing unloading hopper, an ore washing water pipe with small water spray drill holes, and an ore unloading water pipe with small water spray drill holes. The helical blades are welded to the outer periphery of the magnetic cylinder. The magnetic system has 360 degrees of a magnetic wrap angle in the magnetic cylinder and has 270 degrees of a magnetic wrap angle close to the concentrate unloading hopper. Permanent magnets of the magnetic system are arranged on a magnet base from left to right in a ladder shape in an NS screw type and form a screw-type magnetic circuit. The permanent magnetic classificator is suitable for a large-scale production flow process, reduces an investment and a cost, can screen iron ores having a good grade, can be operated simply, is light, has a small covering area, saves energy and is convenient for operation and maintenance.

Description

1. Technical field [0001] The invention relates to a concentrator, in particular to a permanent magnetic concentrator for improving the grade of magnetic materials. 2. Background technology [0002] The existing traditional magnetic separator, its beneficiation process is just a water washing process, the iron ore separated by this kind of magnetic separator has more impurities and low grade, and most of them cannot meet the quality standards required by steel plants. If you want to select good quality iron ore, you must use multiple separators to classify and repeat the selection, which not only increases the workload, but also consumes electricity and water to increase production costs. 3. Contents of the invention [0003] The purpose of the present invention is to provide a permanent magnet magnetic concentrator that can adapt to large batches of assembly line operations, has low production cost, and can produce good-grade ore by using a brand-new method of combining m...

[0002] The existing traditional magnetic separator, its beneficiation process is just a water washing process, the iron ore separated by this kind of magnetic separator has a lot of impurities and low grade, and most of them cannot meet the quality standards required by iron and steel plants

If you want to select high-quality iron ore, you must use multiple separators to classify and repeat the selection, which not only increases the workload, but also consumes electricity and water to increase production costs.
