Double-cylinder magnetite fine powder grade improving machine based on centrifugal force

Abstract

The invention discloses a double-cylinder magnetite fine powder grade improving machine based on centrifugal force. The grade improving machine structurally comprises an ore fine powder outlet, a bracket, a pouring hopper, an iron ore fine powder improving machine body, a top cover and a driving device, wherein the bottom of the iron ore fine powder improving machine body is connected with the pouring hopper with the iron ore fine powder outlet; the pouring hopper is vertically connected with the bracket; and the top of the iron ore fine powder improving machine body is connected with the topcover. Compared with the prior art, the grade improving machine has the beneficial effects that ore pulp can be comprehensively stirred through the combined arrangement of a rotating shaft, a stirringgroup, a double-layer cylinder and a connecting sleeve, the stirring is sufficient, the pulp is enabled to be more uniform, the ore fine powder is prevented from being wrapped by impurities, the orefine powder is prevented from being discharged without being magnetically separated, the waste of the ore fine powder is avoided, magnetic separation is carried out on light ore fine powder through aU-shaped permanent magnet, the ore fine powder is further attracted, the magnetic separation effect is improved, the ore fine powder on the wall of the cylinder body can be scraped off through a scraping plate, the situation that the magnetic force of the fine iron powder is weakened due to the fact that the cylinder body is full of the ore fine powder is avoided, and the magnetic separation is better facilitated.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a centrifugal force-based double-barreled magnetite fine powder grade elevator. Background technique [0002] In the field of mining production and processing, the process of crushing and screening iron ore and separating the grade of refined iron powder is an indispensable and important link. Most of the existing technologies use wet drum magnetic separation for magnetic separation to obtain the grade of ore concentrate powder . [0003] Due to the imperfect technology of the existing wet-type drum magnetic separator, it is only purely separated by stirring, which will cause insufficient stirring of the ore slurry, resulting in uneven slurry, resulting in the mineral concentrate powder being wrapped by impurities, resulting in the mineral concentrate powder being unmagnetic. In addition, with the increase of the magnetic separation time, the area of ​​the fine iron powder wil...

AI Technical Summary

Problems solved by technology

[0003] Due to the imperfect technology of the existing wet-type drum magnetic separator, it is only purely separated by stirring, which will cause insufficient stirring of the ore slurry, resulting in uneven slurry, resulting in the mineral concentrate powder being wrapped by impurities, resulting in the mineral concentrate powder being unmagnetic. In addition, with the increase of the magnetic separation time, the area of ​​the fine iron powder will gradually increase, which will lead to the weakening of the magnetic force of the fine iron powder, which will affect the magnetic separation effect.
