Dry magnetic separator

Abstract

The invention discloses a dry magnetic separator, relates to the technical field of magnetic separator equipment, and solves the common problems that existing dry magnetic separator equipment is too complex and easily breaks down after being used for a long time. The technical scheme is characterized in that the dry magnetic separator comprises a main rack, and the main rack is provided with a feeding port and a discharging port; a magnetic separation assembly is arranged in the main rack; the magnetic separation assembly comprises a material conveying channel and a magnetic part, the magneticpart extends into the material conveying channel and can rotate automatically relative to the material conveying channel, and a first material scraping part and a second material scraping part are arranged outside the material conveying channel; the first material scraping part scrapes the circumferential surface of the magnetic part; and the second material scraping part reciprocates in the self-rotating axis direction of the magnetic part and scrapes the axial surface of the magnetic part. The dry magnetic separator achieves the purposes that mineral substances to be magnetically separatedcan be continuously subjected to multi-stage magnetic separation procedures, the effect and the efficiency of the magnetic separator can be conveniently and effectively improved, the scheme is simpleand practical, the working state is stable, and the dry magnetic separator has the characteristics of low failure rate and high space utilization rate.

Description

technical field [0001] The invention relates to the technical field of magnetic separator equipment, in particular to a dry magnetic separator. Background technique [0002] Dry-type magnetic separator is a kind of magnetic separator that separates in the air and is mainly used for separating large and coarse-grained strong magnetic ores and fine-grained weak magnetic ores. Dry drum magnetic separator is a kind of dry magnetic separation equipment widely used in the mineral processing industry. It is used in multiple process sections such as dry pre-selection, dry roughing and dry beneficiation of iron ore after fine crushing. It can greatly improve the grade of the ore before it is put into the mill, and reduce the power consumption of the mill. For some single strong magnetic ore, it can also directly obtain iron concentrate through several stages of dry separation process. [0003] In order to improve the processing capacity and separation effect of the equipment, two or...

AI Technical Summary

Problems solved by technology

[0003] In order to improve the processing capacity and separation effect of the equipment, two or more magnetic cylinders will be configured on a single dry separation system. Although the ore transfer and ore distribution mechanism is omitted in this way, materials are likely to exist in the connecting area of ​​the magnetic cylinders. The flow is not smooth and the distribution of ore is uneven, so it not only cannot play the separation performance of the equipment, but also easily causes the magnetic separator equipment to be too complicated, and it is prone to failure after long-term use; secondly, there are low separation accuracy, pulse The phenomenon that the stone is easy to be mixed makes it difficult to upgrade the concentrate
