Iron ore screening device

Abstract

The invention belongs to the technical field of ore production equipment, and discloses an iron ore screening device which comprises a base, a screening box is fixedly installed at the top of the base, an ore discharging pipe is arranged on the outer surface of the side face of the screening box, a slag outlet is formed in the side, away from the screening box, of the base, a feeding channel is fixedly installed on the side, away from the ore discharging pipe, of the screening box, and a control panel is fixedly installed over the ore discharging pipe. According to the iron ore screening device, when a collision driving rod moves, a collision conduction rotating support is squeezed; when the collision conduction rotating support is squeezed to deform, an arc-shaped rotating rod is pushed to rotate; and after the arc-shaped rotating rod rotates, a memory elastic piece deforms; when the memory elastic piece deforms, an impact ball is pushed to impact an iron attraction block; and therefore, the purpose of shaking off dust on the surface of the iron attraction block is achieved, and the situation that the magnetism of the iron attraction block is affected due to excessive dust accumulation is prevented.

Description

technical field [0001] The invention relates to the technical field of ore production equipment, in particular to an iron ore screening device. Background technique [0002] Iron ore is an important raw material for iron and steel production enterprises. Natural ore (iron ore) is gradually extracted from natural ore (iron ore) through procedures such as crushing, grinding, magnetic separation, flotation, and gravity separation. Iron ore is a mineral aggregate containing iron element or iron compound that can be used economically. Any ore that contains economically available iron is called iron ore. There are many types of iron ore, mainly magnetite, hematite and siderite are used for ironmaking. After the iron ore sample is dissolved in hydrochloric acid, the iron in it is converted into ferric iron. Under strongly acidic conditions, ferric iron can be reduced to ferrous iron by tin dichloride. After divalent tin has reduced ferric iron, methyl orange can also be reduced ...

AI Technical Summary

Problems solved by technology

[0003] And in the process that iron ore is mined, usually there will be a large amount of crushed ore, these crushed ore are mixed in stone, need to use screening device to screen out these crushed ore from stone, but existing screening device is in During the screening process, there will still be some stones mixed in the crushed ore, resulting in the need to re-screen the ore in the follow-up, which not only affects the screening efficiency of the ore, but also may affect the quality of the crushed ore, and has a negative impact on the subsequent ironmaking. influences
