Grade-adjustable cylindrical magnetic separator

Abstract

The invention relates to a grade-adjustable cylindrical magnetic separator, which comprises an ore feeding box, a separation groove, a separation cylinder, a concentrate box, a concentrate box ore discharge pipe, a tailing box, a tailing box ore discharge pipe and a control box of the cylindrical magnetic separator, and is characterized in that a full-length separation plate is arranged on the tailing box, and a liquid level meter is arranged above a left side box body; a tailing discharging opening of the separation groove is inserted into the right side box body, two long-strip-shaped ore separation openings are formed in a right side plate of the right side box body in a bilateral symmetry mode, two long-strip-shaped ore inlets are formed in a left side plate of the concentrate box, andthe two long-strip-shaped ore inlets are communicated through an ore separation horizontal groove; gate valve clamping grooves are formed in the two ends of the right side box body, a supporting steel beam is arranged at the top of the tailing box, and a gate valve mechanism is arranged between the clamping grooves and the right side plate. The grade-adjustable cylindrical magnetic separator tailings mixed into the concentrate box is controlled by controlling the opening degree of the ore separation opening of the tailing box, so that the grade of concentrate is adjustable, and finally, the grade of high-quality magnetic separation concentrate of single magnetite is controlled to be 68%-69%.

Description

technical field [0001] The invention belongs to the technical field of magnetic separation of ore dressing plants, in particular to a drum-type magnetic separator with adjustable grade. Background technique [0002] At present, most iron ore minerals have a certain degree of magnetism, so magnetic separation is the most important beneficiation method for iron ore. Among them, strong magnetic minerals such as magnetite and titanium magnetite are mostly separated by permanent magnetic drum magnetic separators. select. Magnetite has relatively large reserves at present. For a single magnetite, due to its single mineral type, there is a lack of similar mineral types that interfere with magnetic separation, and some magnetite embedded with coarse particle size is an ore that is very easy to separate. After the individual ores are dissociated, the magnetic separation is carried out with a drum magnetic separator, and the iron grade of the concentrate can generally reach more than ...

AI Technical Summary

Problems solved by technology

Not only is the procurement of raw materials complicated, but also when mixing ore, it is necessary to add low-grade ore resident facilities, feeding and discharging facilities for ore storage facilities, and a mixing yard

The total storage time of general mine facilities and mixing yards generally takes 2-7 days, which will require a large storage space and high infrastructure investment

And the mixing yard also needs to use expensive mixing facilities, such as stackers and reclaimers, and the investment in equipment is also high

All of these greatly increase the investment and operating costs of enterprises
