Deep processing device for magnetic iron ore

Abstract

The invention relates to a deep processing device for magnetic iron ore. The deep processing device comprises a screening system, a deflection crushing system, a vibrating mill system, a sieving system, a multilayer funnel, a fine grinding system, a solid-phase magnetic separation system, a liquid-phase magnetic separation system, a spray-washing system and a washing system, which are arranged from top to bottom in sequence. Raw material vein ore in mining can be preliminarily screened through the screening system, the deep processing device can ensure that a machine cannot be damaged due to the huge size difference of ore in the following processing process. Moreover, according to a scientific processing order, the ore is successively broken from large size to small size through the deflection crushing system, the vibrating mill system and the fine grinding system in sequence, so the processing effect is good, and the wastage rate of a grinding head or crushing components is reduced.By the cooperative work of the sieving system and crushing operation, the deep processing device can ensure that small-size ore cannot enter a large-size crushing process link to jam or damage the machine.

Description

technical field [0001] The invention relates to a mineral processing equipment, in particular to a magnetite ore deep processing device. Background technique [0002] With the development of the times, the country's overall industrial development has ushered in a new upsurge. In this wave of industrialization, new requirements have been put forward for the development of industrial production, among which are the two points of quality first and green development. In the traditional mining industry, these two points are often at the heart of the process and related equipment. For example, it is aimed at synchronous classification and efficient screening in the ore mining process to ensure low raw material loss rate, or try not to use chemical methods in ore classification, which will lead to the generation of a large amount of industrial waste liquid and even waste gas. Magnetite is a main ore raw material in the ironmaking industry, so its mining volume is huge. It refers ...

AI Technical Summary

Problems solved by technology

At present, most of the equipment for deep processing of magnetite has the following problems: (1) For the crushing of ore, most of them use grinding, but in mining, because of the different quality of ore veins, it is easy to cause a huge gap in ore size. However, using a single method of crushing will result in extremely poor results, which will easily affect the processing effect of subsequent processes, and secondly, it will easily lead to machine jamming or even shutdown for maintenance. More importantly, the single grinding process will easily cause grinding head or broken Rapid loss of components, which greatly increases production costs; (2) The current equipment screening process and crushing process are carried out separately, without organic combination, which leads to the fact that the ore crushing effect is generally not mentioned, and even the ore is crushed by chemical methods. Screening and screening will easily lead to the production of a large amount of toxic and harmful waste liquid and waste gas, and secondly, the ore with chemical raw materials will cause great damage to equipment and instruments in the subsequent contact processing; (3) currently using physical Most of the devices for screening ore by the method can only use a single screening method, which can easily lead to insufficient screening and waste of raw materials. Poor, not conducive to subsequent processing and increase the processing cost of subsequent processing
