Preferment strong magnetic separation machine

Abstract

The invention discloses a preferment strong magnetic separation machine which comprises a main body bracket as well as a magnetic roller, a tank body, a pressure water tube and a demineralizing wheel, wherein the magnetic roller comprises a magnetic roller main shaft, a magnetic isolation plate, a counter magnetic plate, a magnetic isolation layer and a magnetic increase plate; the tank body comprises a mineral feeding channel which extends to be below the magnetic roller; the pressure water tube extends to the bottom of the mineral feeding channel below the magnetic roller; the demineralizing wheel comprises a rotating wheel and uniformly distributed comb teeth arranged on the rotating wheel; the rotation direction of the demineralizing wheel is opposite to the rotation direction of the magnetic roller. The machine is not only applicable to weak magnetic iron ore separation (wet separation), but also applicable to separation of weak magnetic ore, such as manganese ore, titanium ore, tantalum-niobium ore and tungsten ore, thus the machine can be popularized to make great contribution to the steel industry and the metallurgical industry of China, and great economic and social benefits can be achieved.

Description

technical field [0001] The invention relates to the field of magnetic separation, in particular to a permanent magnetic separation machine. Background technique [0002] Existing weakly magnetic minerals (especially weakly magnetic iron mineral Fe 2 o 3 ) The commonly used processes in the beneficiation process are flotation (chemical separation) and gravity separation. [0003] The disadvantages of the flotation process are environmental pollution, low beneficiation grade, low ore recovery rate, waste of resources, high beneficiation cost and low production efficiency. The re-election process has the same disadvantages as the flotation process except that it does not cause environmental pollution. [0004] In addition, there is an electromagnetic concentrator. Although the beneficiation effect is equally good, it consumes high energy, is expensive, and has complex operation and high maintenance costs. Contents of the invention [0005] The purpose of this section is to...

AI Technical Summary

Problems solved by technology

[0003] The disadvantage of the flotation process is that it causes environmental pollution, low beneficiation grade, low recovery rate of raw ore, waste of resources, high cost of beneficiation and low production efficiency; except that the re-election process does not cause environmental pollution, other disadvantages are the same as the flotation process

[0004] In addition, there is an electromagnetic concentrator, although the beneficiation effect is equally good, but its energy consumption is high, the cost is high, and the operation is complicated and the maintenance cost is high.
