Description
Affiliated technical field
The present invention relates to a kind of iron ore dressing equipment, is a kind of Wet-type permanent magnet drum type high-purity iron powder extractor that extracts the high smart iron powder of iron-holder from the low iron ore of iron-holder specifically.
Background technology
At occurring in nature, the content of iron has very big difference in the iron ore.Analyze from the mineralogenetic epoch, all there is iron ore to form from Proterozoic Eon to the Cenozoic, the most important with Proterozoic Eon, the type iron ore iron-holder is low, and iron-holder is about 10% to 35% of iron ore, such iron ore, washability is good, even say, can pass through permanent-magnet drum type magnetic separator, improve the iron-holder of iron ore.At present popular permanent-magnet drum type magnetic separator, be provided with permanent magnetic system, the magnetic force that utilizes permanent magnetic system to produce, come on the drum surface that magnetic mineral that iron-holder in the iron ore ore pulp is higher attracts, and along with cylinder rotates together, wait to break away from the magnetic field effect after, under the effect of gravity and scraper plate outside the discharge machine, become the higher smart iron powder of iron-holder, non-magnetic material and/or weakly magnetic material are then discharged from the mine tailing mouth, finish the sorting work of iron ore.The content of iron is at this kind iron ore of 35%, follow the example of by the naughty of above-mentioned permanent-magnet drum type magnetic separator, the content that can obtain iron is at the smart iron powder more than 65%, and iron content is at this kind iron ore below 35%, through obtaining the inferior smart iron powder about 50% after the ore dressing, the iron ore that iron-holder is extremely low, for example iron-holder belongs to a mao ore deposit at the iron ore below 10% and 10%, can not be used at present, thereby abandoned in a large number, if the extremely low iron ore of iron-holder is smelted, then will be consumed a large amount of coal, lime stone, water, resource such as electric power and manpower, lose more than gain real the genus.
Before the present invention finishes, not seeing the Wet-type permanent magnet drum type high-purity iron powder extractor identical with the present invention uses in people's routine work, not seeing the Wet-type permanent magnet drum type high-purity iron powder extractor identical with the present invention has sale, and it is on the books in the literature also not see the Wet-type permanent magnet drum type high-purity iron powder extractor identical with the present invention.
Summary of the invention
The object of the present invention is to provide a kind of Wet-type permanent magnet drum type high-purity iron powder extractor, use this machine to carry out selected to iron ore, iron ore that can iron content is extremely low, extract the high smart iron powder of iron-holder, the use value that disappears, iron ore at the bottom of the iron-holder utmost point that is dropped, for utilizable, the smart iron powder that iron-holder is high, fully save, utilized the iron ore resource at the bottom of the iron-holder utmost point, also indirect saving a large amount of coals that use in the smelting process, lime stone, electric power, water and human resources also can reduce simultaneously because the coals that use in a large number in the smelting of the iron ore low to iron-holder, resources such as lime stone and the sulfur dioxide that produces and emission of carbon-dioxide and to the pollution of natural environment.
