Abstract

The invention discloses a high gradient magnetic separator, which comprises a separation ring and a driving device thereof, an ore feeding device, a concentrated ore discharging device and a concentrated ore collecting device, wherein the separation ring comprises a rotating ring and a concentrated magnetic medium pack, an upper magnetic yoke, an upper magnet, a lower magnetic yoke, a lower magnet, a left magnetic yoke, a right magnetic yoke, and a magnetizing and demagnetizing device which consists of magnetic coils and a magnetizing power source and can perform magnetizing and demagnetizing treatment on the upper magnet and the lower magnet respectively. The high gradient magnetic separator smartly combines a permanent magnet and a magnetizing power source to form a background magnetic field of the separator, so the high gradient magnetic separator can conveniently perform magnetizing and demagnetizing treatment on the upper magnet and the lower magnet according to the required value of the background magnetic field and then perform effective separation on ores after canceling the magnetizing power source when in work, and can perform demagnetizing treatment on an upper magnet and a lower magnet when in assembly and maintenance so as to solve the magnetic blockage problem. The high gradient magnetic separator can greatly reduce the energy consumption, and fully ensure convenient maintenance in practical production.

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...
