Embodiment 1

[0039] like image 3 As shown, the air outlet pipe 3 of one magnetic separator main body is connected to the air inlet pipe 1 of another magnetic separator main body, forming a series structure. The main bodies of multiple magnetic separators can be connected in series to form multiple magnetic separations to obtain better magnetic separation effects.

Embodiment 2

[0041] like Figure 4 and Figure 5 Shown:

[0042] When in use, the mode of arraying magnetic separators in a matrix can also be adopted to add an air collecting pipe 11 and an air distribution pipe 10. The air distribution pipe 10 can divide a nozzle into multiple interfaces, and the air collecting pipe 11 can Combines multiple interfaces into one nozzle. The air collecting pipe 11 is connected to the air outlet pipe 3 , and the air distribution pipe 10 is connected to the air inlet pipe 1 . Arrange several magnetic separator bodies in a matrix, such as arranging 9 magnetic separator bodies in a 3x3 array, then connect the outlet pipes 3 of the 9 magnetic separator bodies with the manifold 11, and connect the 9 The air inlet pipe 1 of each magnetic separator body is connected with the air distribution pipe 10.

[0043] The air distribution pipe is connected to the large amount of gas provided by the high-pressure roller mill system after roller pressure separation, and s...

Embodiment 3

[0045] When in use, a magnetic separator combined in series and matrix arrangement can also be used. The air outlet pipe 3 of the main body of a magnetic separator is connected with the air inlet pipe 1 of the main body of another magnetic separator to form a series structure. Several The main body of the magnetic separator is arranged in a matrix array after being connected in series.

[0046] In this way, a better magnetic separation effect can be obtained and the processing capacity of the magnetic separator can be enhanced at the same time.

Abstract

The invention discloses a micro powder fine powder dry-type magnet separator. The dry-type magnet separator comprises a magnet separator main body. The magnet separator main body comprises an air inlet pipe, a non-magnetic-conductive air pipe, an air outlet pipe, a magnetic system, and an ore discharging pipe. The air inlet pipe communicates with one end of the non-magnetic-conductive air pipe. The other end of the non-magnetic-conductive air pipe communicates with the air outlet pipe. The ore discharging pipe is arranged below the non-magnetic-conductive air pipe. One end of the ore discharging pipe communicates with the non-magnetic-conductive air pipe. The magnetic system is arranged on the outer side of the non-magnetic-conductive air pipe. With the dry-type magnet separator, micro powder and fine powder can be processed continuously, and no subsequent equipment is needed. The energy consumption of the whole magnet separator is low. The ore recovery rate after magnet separator is high, and the sorting purity is high. No pollution is caused during the separation process and after separation, such that the separation process and the post-separation process are environment-friendly. Specifically, the dry-type magnet separator provided by the invention can carry out rapid, sufficient, and comprehensive separation. The treatment amount is large, the sorting efficiency is high, the iron ore grade is high, and the energy consumption is low. No water is needed in the whole process, such that water pollution is avoided. Tailings are collected by a dust collector, and are discharged, such that no air pollution is caused.

Description

technical field [0001] The invention relates to a fine powder and fine powder dry magnetic separator, which belongs to the technical field of magnetic separators. Background technique [0002] In metallurgy, mining and other mineral processing fields, it is necessary to sort magnetic materials, such as sorting iron ore. The characteristics of iron ore in my country are "poor, fine, and miscellaneous", and most iron ore are located in arid and rainless areas, and the cost of water is extremely high; and the particle size of the minerals is fine, and the cost of grinding is high. It is almost impossible to use wet sorting, because under the premise of wet fine grinding and classification, a large number of fine particles are produced, and the specific surface area of ​​the particles increases greatly, which makes it difficult to dehydrate the products after wet sorting, and the moisture content of magnetic products is relatively high. , requires additional drying operations, ...
