Problems solved by technology

[0005] Chinese patent 02134298.9 discloses a dual-frequency pulse double vertical ring high-gradient magnetic separator, which adopts the separation space of horizontal magnetic force lines formed by the left and right magnetic poles and the outer edge of the turntable, and can make the pulp in this space produce and The combination of the dual-frequency pulse device with the direction of the magnetic field line perpendicular to each other can make the difference between the force of the fluid dynamics generated by the pulp pulse and the magnetic force generated by the magnetic field on different magnetic mineral particle groups in different sections of the separation space of the magnetic separator. Efficient separation is obtained, but its concentrate unloading device is also washed with separate water
To sum up, in all these vertical-ring high-gradient magnetic separators, concentrate unloading is carried out by washing with separate water. Since the magnetic gathering medium is composed of multi-layered relatively dense rods and nets, so When flushing, only a large amount of water can be used to improve its unloading effect. Ho

Abstract

The invention relates to a high-gradient magnetic selector, which comprises selecting ring, driver, mineral feeder, fine mineral discharger, and fine mineral collector, wherein the selecting ring comprises rotation ring, accumulation medium stack, upper magnetic pole, lower magnetic pole and active coil; the discharger comprises parallel hydraulic discharger and wind discharger at the outer side of rotation ring, while they are relative to the fine mineral collector at the inner side of rotation ring. The invention combines water washing and wind washing to effectively remove the magnetic particles on the magnetic collecting mediums, to improve the mineral discharge efficiency. The invention can save water resource and improve the mineral slurry density.

Description

technical field [0001] The invention relates to a magnetic separator for ore dressing, in particular to a high-gradient magnetic separator. Background technique [0002] The proposal of high gradient magnetic separation theory has brought a qualitative leap to the field of magnetic separation, increasing the types of minerals that can be magnetically separated, and widening the upper and lower limits of particle size. Early high-gradient magnetic separators are periodic, also known as magnetic filters, and this type of equipment is widely used in occasions with extremely low magnetic content and very fine particle size. The continuous high gradient magnetic separators that appeared immediately include electromagnetic flat ring strong magnetic high gradient magnetic separators, permanent magnet and electromagnetic double vertical ring high gradient magnetic separators. Electromagnetic flat-ring high-gradient magnetic separator is easy to cause mechanical blockage because the...
