Description
Technical field
The utility model relates to the technique of preparing field, relates in particular to a kind of high pressure selection by winnowing concentration equipment of half fine ore.
Background technology
The lower ore of valuable metal grade is through mechanical enrichment or physical enrichment, process as ore dressing process such as radiometric sorting, gravitational method ore dressing, flotation, obtain the higher ore of valuable metal grade of certain productive rate, this part enrichment the ore of valuable metal be concentrate.
The iron ore concentrate extracting method of prior art is: iron ore enters the ball mill ball milling through crusher in crushing is laggard, then the iron ore particle after ball milling adds a large amount of water to form ore pulp, then with wet magnetic separator, ore pulp is carried out wet magnetic separation and extracts iron ore concentrate.This extracting mode of iron ore concentrate not only needs to consume the water resource of a large amount of preciousnesses, causes the waste of water resource, and the Tailings Slurry that forms in leaching process also can pollute the water quality of surrounding environment.Particularly for the iron ore of the arid area of the water resource famines such as desert, minery and the ore dressing district several hundred kilometers of often being separated by, need and to extract iron ore concentrate in the ore dressing district that the raw ore of adopting without the minery at water source is transported to the water source, freight is high, extraction cost is high, and the mode of wet magnetic separation extraction iron ore concentrate has limited the exploitation scale of arid area iron ore deposit.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of high pressure selection by winnowing concentration equipment is provided, reaches the purpose of anhydrous extraction concentrate, the water resource that avoids waste reduces the water pollution to surrounding environment.
For solving the problems of the technologies described above, the technical solution of the utility model is, high pressure selection by winnowing concentration equipment comprises: the dry type cleaning magnetic separator, described dry type cleaning magnetic separator is provided with case outward, offer material inlet on the antetheca of described case, below corresponding to described material inlet on the antetheca of described case offers the high-pressure blast air inlet, and described high-pressure blast air inlet is obliquely installed from bottom to top in the inboard of described case antetheca, is provided with open top on the roof of described case.
As preferably, be provided with rear aperture on the rear wall of described case, pass for delivery of the concentrate ribbon conveyer of concentrate the below that described rear aperture and its feed end correspondence are arranged at the concentrate exit side of described dry type cleaning magnetic separator.
Owing to having adopted technique scheme, high pressure selection by winnowing concentration equipment of the present utility model is provided with case outside the dry type cleaning magnetic separator, offer material inlet on the antetheca of case, offering the high-pressure blast air inlet below corresponding to material inlet on the antetheca of case, this high-pressure blast air inlet is obliquely installed from bottom to top in the inboard of case antetheca, is provided with open top on the roof of case; When carrying out the magnetic separation of high pressure selection by winnowing, tilt to be blown into high-pressure blast from the high-pressure blast air inlet from bottom to top in case, high-pressure blast blows to the dry type cleaning magnetic separator with half fine ore in the whereabouts in material inlet enters case, wherein the bulky grain mine tailing in half fine ore falls to the bottom of case in the self gravitation effect, fine grained mine tailing lighter in half fine ore is discharged with the wind from the open top of case, fine ore in half fine ore is adsorbed by the dry type cleaning magnetic separator, thereby finally extracts fine ore.
High pressure selection by winnowing concentration equipment of the present utility model has been broken away from the concentrate leaching process the dependence of water resource, has removed the link of water, has avoided the waste of water resource, has reduced the water pollution to surrounding environment.The raw ore that especially can satisfy the arid areas such as desert can extract fine ore in the minery without the water source, has reduced cost of transportation and extraction cost.
