Etc. the stock grading of grade.And there is the equipment preferable scattering and grading to act on to the adhesional wetting materiel with certain moisture, right
In adhesional wetting materiel, in addition to being acted on scattering and grading, also there is enforced classification, unique structure is sieved using scattering and grading
The small particles material adhered on bulky grain is forced to scrape, even if material also can because sticky adhesive is broken up in mechanism in the first order
Excluded under the pressure discharge effect that multistage breaks up mechanism.Using this equipment with regard to that can solve material scattering and classification after high pressure roller mill
The problem of.
Optimize industrial design, the technical scheme for reducing system dust pollution is such：Conventional high-tension roller mill is broken up closed circuit
The main airborne dust point of grinding system is during high pressure roller mill operation, screening operation and material transfer.High-pressure roller mill（Roller
Press）Using closing choke feeding, extrude at a slow speed, Dust Capacity caused by itself is minimum, and its airborne dust results from upper end constant weight
Storehouse is fed and lower end discharging.Scattering and grading is sieved due to having the function that to break up, it is not necessary to needed as vibratory sieve it is higher to
Material height, this is greatly lowered the generation of dust, then has scattering and grading sieve to be classified using the wheel 513 of breaing up of rotation, if
It is standby not vibrate, material also will not violent oscillatory motion, greatly reduce the generation of dust, can only be produced in discharging and classification process
A small amount of airborne dust.The main generation point of airborne dust is in the transport process in material, and at large scale industry scene, material transfer is mainly adopted
With belt conveyor, due to the relation of the discrepancy in elevation between equipment in the material feeding of belt and discharge process, a large amount of dust can be produced.It is right
Airborne dust point more than transports distance between operation by shortening, and reloading point is highly reduced, and sets dust cover to thing
The measure of material closing transhipment, can greatly reduce the generation of airborne dust.Dedusting, water mist dust-removing system are carried out using water mist dust-removing system
With the characteristics of reduced investment, operating cost is low.
Scattering and grading sieve operation principle such as 1-2 figures, compared with traditional shaker and intersecting sieve, the sieve feed end to discharging section
Using the installation that is inclined upwardly.Traditional shaker and intersection sieve are using the mounting means tilted down, and so installation is for profit
Vibration and free-fall velocity with equipment, allow material to pass through screening surface.But simultaneously because vibration and acceleration of gravity presence,
Material can be increasingly faster by speed, and the elasticity of erratic behavior and screen cloth due to being hit between material when vibrating in itself,
Under a part of fine particle stage material sieve more difficult to get access.And 5 unique upward motion mode of scattering and grading sieve coordinates tooth form to break up wheel energy
Material is communicated up step by step, material is ceaselessly rolled in transmittance process, and the material less than sieve aperture can be broken up wheel leading portion
Small tooth is taken under sieve by force.Tooth form, which breaks up wheel, also has the effect of breaing up, due to breaing up the limitation of size of wheel, the excessive nothing of material cake 55
Method is communicated up, and is broken up the continuous shock of wheel by tooth form in the storage end of scattering and grading sieve and is disperseed, is finally completely dispersed.Should
Tooth form, which breaks up wheel, also has sieve aperture clearing function, will be stuck in the material broken up between wheel and remove by force, and this feature is glued wet in processing
Acquired a special sense during material, adhesional wetting materiel has very strong adhesive capacity, can adhere on wheel is broken up, be sieved using scattering and grading
Self-cleaning function, the feasibility that adhesional wetting materiel is sieved is can guarantee that, adhesional wetting materiel is used high-pressure roller mill（Roll squeezer）Enter
Row closed-circuit grinding turns into feasible.
Fig. 1 is the system flow of high pressure roller mill scattering and grading closed-circuit grinding environment friendly system, and the flow is ground with conventional high-tension roller
Closed-circuit grinding flow has more complicated transhipment link compared to greatly simplifying between conventional high-tension roller mill and subsequent hierarchical operation,
And need to design surge bunker before screening operation to balance and distribute the feed of screening.And the flow that we design turns centre
Transport link to simplify, only need an outfeed belt can that the material after extruding is sent into scattering and grading sieve, or even allow in the discrepancy in elevation
In the case of, material after extruding can be directly given to scattering and grading sieve.The simplification of flow will bring the reduction and management of investment
Simplification, bring economic benefit for industry spot.
All airborne dust points of the flow use water mist dust-removing, and in order to coordinate water mist dust-removing, each material transfer point is using envelope
Input and output material design is closed, increases to be reduced by material space and is arranged outside air-flow.Material falling height is reduced simultaneously, reduces airborne dust.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
