Description
Technical field
The invention belongs to be sintered screening (magnetic mine dry separation screening) technical field, in particular to a kind of magnetic mine dry separation classification
Vibrating screen.
Background technique
Being crushed in country's beneficiation flowsheet at present is mostly three section of one closed circuit conventional flow that coarse crushing, middle fine crushing add screening operation
Broken, middle crushed product feeds sieving circuit in the entrance of journey, i.e. coarse crushing product, and the oversize after screening is into fine crushing, carefully
Crushed product feeds sieving circuit again, and undersize enters mill choosing.Screening plant for traditional technique of preparing is vibrating screen,
It is mainly made of screen box, electric-motor drive device, vibrator, vibration absorber and compass screen surface, is slowed down by motor by belt
Device directly drives the revolution of the chunking eccentric type vibrator in the middle part of screen box, and the centrifugal intertia force that eccentric block generates pacifies inclination
The screen box of dress does circular motion in the case where four groups of shock-absorbing springs support, and material vibrates throwing from feeding end to discharge end, realizes
Layering and saturating sieve mesh, to play the role of that Mineral Classification therein will be fed, due to the limitation of traditional shaker function, give
Mineral grain can only be classified by the product for entering traditional shaker in screen box, obtain oversize and undersize, without
The mineral for not needing screening temporarily can be retained according to demand, that is to say, that by the mineral of screening machine in traditional technology
Under the conditions of can only be forced to be classified, this result in such as by be not required in process screening material feed screening machine, not only increase
The load of screening plant operation, reduces screening efficiency, and cause the waste of resource.And if the material that screening will not needed
Do not enter screening plant, be just necessarily required to special belt feeder and transported the partial material, this also has led to belt fortune
The engineering construction cost of transfer device.In addition, in order to enable the product for sieving ore storage bin normally to feed screening machine, it is necessary to which screening is made
The Ore Hopper of industry reaches 45 ° or more, and the height difference demand that this is allowed between screening is higher, this undoubtedly also increases workshop between screening
Construction cost.
Summary of the invention
The object of the present invention is to provide one kind to be able to satisfy various sizing requirements, and structure is simple, wear-resistant, service life
It is long, have space occupied small, the convenient feature of haul, the magnetic mine dry separation classification of the wear-resistant selectivity for keeping sieve plate screening efficiency high
Vibrating screen.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of magnetic mine dry separation grading oscillating screen of the invention, including screen box, sieve plate, support, vibrator, shock-absorbing spring,
Transmission gear for electric motor and control device, it is characterised in that: blind plate beam is equipped in the upper middle position of screen box, the two of blind plate beam
Side is equipped with track, and the top of track is arranged in by idler wheel for blind plate, and the blind plate is by the flexible blind plate institute of upper layer blind plate and lower layer
Blind plate stretches by being placed under the blind plate of upper layer in composition, the ladder-like blind plate that the upper layer blind plate is three layers or more, the lower layer
The straight blind plate in portion, setting are formed in straight blind plate tail portion for controlling the flexible adjustable spring of straight blind plate and rotating handles.
Further, the upper layer blind plate is four to five layers.
Further, each layer of the upper layer blind plate is 200mm-250mm, having a size of 5000mm × 5487mm, installation
20 ° -22 ° of inclination angle.
The invention has the advantages that
(1) structure is simple, and installation and maintenance are quite convenient to；
(2) blind plate is provided on the top of screen box due to the present invention, non magnetic ore channel can be constructed by blind plate,
So that non magnetic ore is directly entered non magnetic ore collecting bin, reduce sieve plate (for the extra load in this part of non magnetic ore)
Screening amount；
(3) since upper layer blind plate is stepped arrangement, non magnetic ore will form accumulation on blind plate, in the process of sorting
The middle form for forming " material dnockout ", to realize wear-resistant effect；
(4) adjustable spring device can be controlled by rotating handles to adjust stretching for lower layer's blind plate according to the speed to mine belt feeder
Contracting length, to realize control sorting supplied materials；
(5) material for not needing screening is separated in advance, saves special belt feeder and is transported the partial material
The step of, to save the engineering construction cost of belt transporting facility, shorten process；
(6) product for sieving ore storage bin can normally feed screening machine, avoid in the Ore Hopper angle of screening operation
Limitation reduces the height difference demand between screening, this undoubtedly also increases the construction cost of workshop between screening.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of magnetic mine dry separation grading oscillating screen of the present invention.
Fig. 2 is the top view of Fig. 1 of the present invention.
Specific embodiment
As depicted in figs. 1 and 2, a kind of magnetic mine dry separation grading oscillating screen of the invention, including screen box 1, sieve plate 6, support
2, vibrator 5, shock-absorbing spring 3, transmission gear for electric motor 4 and control device, it is characterised in that: in the upper middle position of screen box 1
Equipped with blind plate beam 13, it is equipped with track 9 in the two sides of blind plate beam 13, the top of track 9 is arranged in by idler wheel 8 for blind plate, described
Blind plate is made of the flexible blind plate of upper layer blind plate 10 and lower layer, the ladder-like blind plate that the upper layer blind plate 10 is three layers or more,
It can also be four to five layers, each layer of the upper layer blind plate 10 is 200mm-250mm, having a size of 5000mm × 5487mm,
20 ° -22 ° of mounted angle, since non magnetic mineral aggregate does not have magnetic action when work, go out in the throwing of fine ore dry separator front end
Come, fallen on above the blind plate of upper layer by funnel, since upper layer blind plate upper layer is stepped arrangement, mistake of the non magnetic ore in sorting
The form of " material dnockout " is formed in journey, to realize wear-resistant effect, while being directly entered by upper layer blind plate 10 non magnetic
Mineral collecting bin reduces the screening amount of sieve plate 6.
Blind plate stretches by being placed in the straight blind plate 11 of upper layer blind plate lower part in lower layer of the present invention, is arranged in straight 11 tail of blind plate
Portion, the adjustable spring 7 flexible for the straight blind plate 11 of control and rotating handles 12 are formed.Blind plate stretches by rotating handle in lower layer
The rotation control adjustable spring 7 of hand 12 stretches, to drive the flexible blind plate of lower layer flexible.
Adjustable spring 7 can be controlled by rotating handles 12 to adjust the straight blind plate 11 of lower layer's blind plate according to the speed to mine belt feeder
Collapsing length, thus realize control sorting supplied materials.
Three kinds of products can produce using magnetic mine dry separation grading oscillating screen of the invention, it may be assumed that non magnetic mineral aggregate；It is produced on sieve
Product and undersize produce on sieve respectively by the way that the non magnetic mine belt feeder of the lower part of magnetic mine dry separation grading oscillating screen is arranged in
Product sealing-tape machine and undersize sealing-tape machine are transported to respective feed bin.
