Description
Technical field
This utility model relates to mineral manufacture field, and is a kind of fluidization vertical screening equipment.
Background technology
Mining screen subset is generally used for the stock grading of 0～300mm.For coarsely graded screening, sieve plate can be used,
Screening is easier to, and sieve plate is the longest for service life, commonly uses in the muck operation select factory.But after grinding operation
The screening operation of particulate and microfine is inefficient, is primarily due to dusting cover sieve aperture the least, sieves to reach certain percent opening
Silk is very thin, and this allows for sieve aperture in dusting cover operation and easily blocks up, and particularly containing the situation that mud is higher, the walk on sieve is easily stuck with paste sieve and made sieve
Son is ineffective.It addition, the coarse fraction on Shai is not only to silk screen serious wear, and it is deposited on compass screen surface and seriously stops fine fraction
Sieve thoroughly.Therefore, screening operation all has strict demand, coarse fraction content not to allow height to ore deposit fineness, and every day will clean
Screen cloth so that the operation management of dusting cover is loaded down with trivial details, and screening efficiency also is difficult to stable.Many selects factory because being reluctant to use dusting cover,
And use hydraulic classiciation, but hydraulic classiciation is not by the physical dimension classification of Ore, but press the fractionation by sedimentation velocity of ore particle,
Sedimentation velocity is affected by Ore density, when making the density variation between partition size inaccuracy, especially Ore the biggest, and waterpower
Classification is the most inaccurate, and heavy mineral can be caused in grinding-classification operation overground, and index can be caused in sorting operation to decline.
Existing dusting cover equipment, the most frequently used effect is preferably high frequency shale shaker, and screen cloth is laterally disposed, with the horizontal relatively
Little angle, after ore pulp feeds screen cloth, makes fine fraction sieve by the dither of screen cloth, and coarse fraction piles up on screen cloth, is shaking
Gradually slide out compass screen surface with screen cloth for supporting bable tops under action.
Current dusting cover screen cloth material is mainly polyurethane, the most wear-resisting.Although stainless steel mesh percent opening is more greatly, but resistance to
Mill property is the poorest, and service life is short the most several days, about 15 days at most, and it is big that workload changed by screen cloth, and every day rinses.Polyurethane screen
Net, one is fixed screen deck, percent opening less than 10%, this apply in recent years fewer and feweri, if its use cycle keep sieve aperture chi
If very little, at about one month, the sieve plate of such as about 0.15mm.Two is the sieve being applied on vibrating scalper, at present, mainly
It is that this application is in the majority with 0.10-2.0mm sieve aperture, wherein with 0.11-based on MICHAEL DRAKE screen cloth and imitated MICHAEL DRAKE screen cloth
0.18mm sieve aperture is most.This kind of sieve substantially requires that feed preparation unit size controls at-200 mesh more than 60%, so service life is relatively
Long, the use cycle of MICHAEL DRAKE screen cloth can reach half a year or longer.Although imitated MICHAEL DRAKE screen cloth profile is the same, subject matter
Being that sieve aperture easily blocks, screen-penetrating performance is deteriorated.MICHAEL DRAKE screen cloth, if controlled well to ore deposit fineness, can reach six or seven ten percent
Screening efficiency, and sieve aperture is not easily blocked, the screening efficiency of imitated MICHAEL DRAKE screen cloth also can reach within a certain period of time 40% with
On.But, the price of MICHAEL DRAKE screen cloth is expensive, every screen cloth (about 0.7m2) close prices ten thousand yuan, be domestic imitative MICHAEL DRAKE sieve
About 2.5 times of net.
The above-mentioned various deficiencies existed due to dusting cover equipment so that mine concentrator many should use the operation of sieve classification
It is forced to use hydraulic classiciation, such as cyclone, spiral classifier, sloping plate grading etc..If dusting cover equipment can overcome above-mentioned deficiency,
Making screening efficiency high and stablize, screen cloth is safeguarded simple, price again cheaply, even to be not strict with to ore deposit fineness can be direct
For classification closed circuit with grinding machine, the important indicator of this Neng Shixuan factory undoubtedly is greatly improved, and its market prospect will be the most considerable.
