Description

. I : . I:

Изобретение относитс к области обогащени полезных ископаемых н может быть использовано при Mart Tном обогащении сильномагнитных железных руд.The invention relates to the field of mineral processing and can be used in Mart Tnom enrichment of highly magnetic iron ores.

Известен барабанный сепаратор дл мокрого обогащени грубойзмельченных сильномагнитных руд, состо щий из вращающегос пустотельного немагнитного барабана, магнитной системы, противоточной ванны, загрузочного и разгрузочного устройств A drum separator is known for wet enrichment of coarsely divided highly magnetic ores consisting of a rotating hollow non-magnetic drum, a magnetic system, a countercurrent bath, loading and unloading devices.

Недостатком такого сепаратора вл етс низка эффективность процесса сепарации по причине механического захвата немагнитных частиц магнитиыми .The disadvantage of such a separator is the low efficiency of the separation process due to the mechanical trapping of non-magnetic particles by magnetic.

Наиболее близким к изобретению по технической сущности и достигаемому эффекту вл етс барабанный магнитный сепаратор дл сильномагнит ных руд, включающий немагнитный барабан , установленный с вoзмo)ннoctью вращени , магнитную системул размеThe closest to the invention in technical essence and the achieved effect is a drum magnetic separator for highly magnetic ores, including a non-magnetic drum, installed with the potential of rotation, a magnetic system size

Недостатками этого сепаратора вл етс ограниченность применени из-за непригодности ванны сциркул цией концентрата дл обогащени The disadvantages of this separator are the limited use due to the unsuitability of the bath by circulating the concentrate for enrichment.

10 трубозернистого материала, кроме того, малый угол наклона патрубков, вызывает их засорение даже на тонг коизмельченном материале и резко снижает эксплуатационную надежность 10 pipe material, in addition, a small angle of inclination of the pipes, causing them to clog even on the ground material and sharply reduce operational reliability

Целью изобретени вл етс повышение эффективности процесса сепарации грубозернистого материала.The aim of the invention is to increase the efficiency of the separation process of coarse-grained material.

Claims

This is achieved by the fact that the nozzles for circulating the magnetic product are dispersed in the feed loading zone and are installed vertically, with the upper part of the nozzle being provided with funnels, which may be pyramidal or conical. Figure 1 shows the proposed separator, a General view; 2, installation of pipes with funnels, and axonometry. A drum magnetic seperator for enriching coarse-grained highly magnetic ores consists of a device 1 for loading the power supply, consisting of supply pipes 2, a countercurrent bath 3f of a rotating hollow non-magnetic drum with a magnetic or electromagnetic system 5 placed in it, receiving chute 6 for a concentrate, vertical pipes 7 with conical or pyramidal funnels 8 for circulating the magnetic product, plugs 9 for closing the nozzles 7, splashed 10 for flushing the concentrate from the drum. Drum separator works as follows. The pulp through the loading device 1 through the nozzles 2 enters the countercurrent bath 3. Under the influence of the magnetic system 5, the magnetic product is attracted to the rotating drum 4; you enter them into the receiving chute 6 for the concentrate. When the concentrate was dropped into the receiving chute 6 under the influence of water, 10 part of it (at the drop point) squirted through the circulating spouts 8 and the nozzles 7 returned to the working zone of the separator where it was re-enriched. The amount of magnetic product returned to the bath is regulated by changing the ratio of closed plugs 9 and open nozzles .7, which contributes to the improvement of the quality of the concentrate and the efficiency of the process of wet magnetic separation. $ 4 The use of a separator of the proposed design with a countercurrent bath for coarse-grained materials will reduce the number of cleanings, which will increase the efficiency of the separation process. Claim 1. Drum magnetic separator for highly magnetic ores, including a non-magnetic drum, mounted for rotation, a magnetic system placed in the drum, devices for loading t 1 tani and unloading separation products, bath, b | zhgla, installed in the concentrate discharge zone, the circulation of the magnetic product, characterized in that, in order to increase the efficiency of the separation process of the coarse-grained material, the pipes for the circulation of the magnetic product are located in the zone feed loads and are installed vertically, and in the upper part the pipes are provided with funnels. 2. The separator according to claim 1, wherein the funnels have a pyramidal shape. 3. The separator according to claim 1., about t l and that the funnels have a conical shape.
