Description

Изобретение относитс к обогащению полезных ископаемых, в частности к конструкции магнитных сепараторов дл разделени сильномагнитных руд и материалов.The invention relates to the beneficiation of minerals, in particular, to the design of magnetic separators for the separation of highly magnetic ores and materials.

.По основному авт. св. 755309, известен магнитный сепаратор, содержащий транспортирующий орган с вибратором , выполненным в виде роликов с дебалансами, расположенный над ним рабочий орган, выполненный в виде установленного параллельно продольной оси транспортирующего органа барабана, в котором размещена маг( нитна система, питатель, приемники продуктов разделени , приспособление дл регулировки зазора между транспортирующим и рабочим органом 1 3.According to the main author. St. 755309, a magnetic separator is known that contains a transporting body with a vibrator made in the form of rollers with unbalances, a working body located above it, made in the form of a drum transporting body installed parallel to the longitudinal axis in which the magician is placed (filament system, feeder, receivers of separation products, a device for adjusting the gap between the transporting and the working body 1 3.

Недостатками этого сепаратора вл ютс невысока эффективность разделени и низкое извлечение. Это вызвано тем, что вибратор не обеспечивает достаточного выброса магнитных частиц.из нижних, прилегающих к ленте, слоев материала, в верхний слой, вследствие чегонижний СЛОЙ материала не подвергаетс разделению в рабочей зоне сепарйтора.The disadvantages of this separator are low separation efficiency and low recovery. This is because the vibrator does not provide sufficient ejection of magnetic particles. From the lower layers of material adjacent to the tape, to the upper layer, due to the low LAYER of the material, does not undergo separation in the separator working area.

Цель изобретени - повышение эффективности процесса сепарации за счет повышени извлечени магнитных частиц в концентрат.The purpose of the invention is to increase the efficiency of the separation process by increasing the extraction of magnetic particles in the concentrate.

Поставленна цель достигаетс тем, что в сепараторе часть роликов снабжена магнитными дипол ми, установлена с чередованием с другой частью роликов, при этом ролики выполнены The goal is achieved by the fact that in the separator part of the rollers is provided with magnetic dipoles, installed alternating with another part of the rollers, while the rollers are made

10 из немагнитного материала, а ролики с магнитными дипол ми снабжены самосто тельным приводом.10 of a nonmagnetic material, and the rollers with magnetic dipoles are equipped with an independent drive.

На фиг. 1 изображена принципиальна схема сепаратора; на фиг. 2 15 разрез А-А на фиг.1.FIG. 1 is a schematic diagram of a separator; in fig. 2 15 section aa in figure 1.

Магнитный сепаратор включает питатель 1, транспортирующий орган 2, раму 3 дл подвески барабана 4 из немагнитного материала, продольные The magnetic separator includes a feeder 1, a transport body 2, a frame 3 for suspending the drum 4 from a non-magnetic material, longitudinal

20 ребра 5 на барабане, магнитную систему 6, вибраторы в виде немагнитных роликов 7, часть из которых снабжена магнитными дипол ми 8, а друга часть - дебалансами, приспособление 9 20 ribs 5 on the drum, magnetic system 6, vibrators in the form of non-magnetic rollers 7, some of which are equipped with magnetic dipoles 8, and the other part - unbalances, special tool 9

25 дл регулировки зазора между барабаном 4 и транспортирующим органом 2, приемник 10 концентрата, самосто тельный привод 11 врадени роликов с дипол ми. Ролики с дипол ми 25 for adjusting the gap between the drum 4 and the transporting body 2, the concentrate receiver 10, and the independent drive 11 driving rollers with dipoles. Dipole rolls

Claims

30 are located slightly below the rollers with unbalances, with the largest removal of the roller with a dipole from the belt surface in the zone of the feeder, and the largest. less - at the end of the working zone. Dipole rollers and debalance rollers alternate. In order to create a high frequency alternating magnetic field with the help of permanent magnets, the rotation frequency of the rollers with dipoles must exceed the rotation frequency of the rollers with unbalances and be greater than 25 rpm. The magnetic separator operates as follows. The source material is fed by the feeder 1 to the transporting body 2 and moves through the vibrating zone created by the unbalance rollers (vibrators) and the alternating magnetic field zone formed by rotating the rollers with dipole 8. Under the action of the vibrator, the material is tossed and loosened, and under the influence of the alternating magnetic field Polar particles are ejected into the upper layers, i.e. Pre-magnetic delamination of the material on the upper strongly magnetic and lower weakly magnetic layer occurs. The stratified material enters the working zone of the magnesium separator, where under the action of the magnetic field created by the magnet system 6, the magnetic particles are attracted to the drum 4 and transported by the longitudinal ribs 5 to the concentrate receiver 10. The rotation of the drum 4 can be carried out both clockwise and against it. The material remaining on the transporting body (the tape moves and under the action of the roller with unbalances and the dipoles 8 loosens and stratifies further, which allows the extraction of magnetic particles to continue along the length of the drum. Depending on the load, the gap between the drum 4 and the transporting body 2 is adjusted by a special device 9. The self-driving drive 11 of the rotation of the rollers with dipoles 8 creates a high-frequency alternating magnetic drive under the transporting body. ix through the transport authority

2. The supply of the proposed separator with rollers with magnetic dipoles in alternation with rollers with unbalances increases the extraction of magnetic particles in concentration and, consequently, the efficiency of the separation process. Claims Magnetic separator according to the author, St. 755309, differing in the fact that, in order to increase the efficiency of the separation process by increasing the extraction of magnetic particles in the concentrate, some of the rollers are equipped with magnetic dipoles and installed alternately with another part of the rollers, while the rollers are made of non-magnetic material, and the rollers with magnetic dipoles are equipped with an independent drive.
