Description
Technical field
The present invention relates to coal separation technical field more particularly to a kind of coal jigging system and methods.
Background technology
The quality of coal separation result, except the factors such as structure, operation with raw coal property, sorting machine itself have outside the Pass,
Largely additionally depend on process coal preparation flowsheet.Existing coal separation flow mainly has full weight media separation flow, full jigging point
Select flow and dense media+jigging flow.Wherein, full weight media separation flow be strictly by density separation, grain graininess and
Shape influences the speed of sorting, although can reach good separating effect, is detrimental to save resource and the energy.Full jigging
The shortcomings that flow, is mainly reflected in difficult separation coal and poor to the coal separating effect that granularmetric composition is thin and smalls content is big, sieves thoroughly
Seriously, cleaned coal loss is larger.The feeding of dense media+jigging flow is big, and repetition sorting amount is larger, and production cost is high.
Invention content
In order to solve the above technical problems, The present invention provides a kind of coal jigging system and methods.
The present invention includes following technical scheme：A kind of coal jigging system, including set gradually multistage jigging machine, dense medium
Any one in matter cyclone or smalls jigging machine the two and separation of coarse slime machine；The multistage jigging machine is three-stage, packet
Gangue sorting section, middle coal sorting section and cleaned coal sorting section are included, the material after tentatively sorting is carried out by three-stage jigging machine and is sent into
Secondary sorting, the material obtained through secondary sorting are carried out to any one in heavy medium cyclone or smalls jigging machine the two
It is sorted again into separation of coarse slime machine.
In addition, the present invention also provides a kind of methods carrying out coal jigging using above-mentioned coal jigging system, including such as
Lower step：
(1) prepare multistage jigging machine and complete bed, fill water；The multistage jigging machine is three-stage, including spoil point
Selections, middle coal sorting section and cleaned coal sorting section；
(2) prepare any one in heavy medium cyclone or smalls jigging machine the two and separation of coarse slime machine；
(3) raw coal is added to the feed inlet of multistage jigging machine, obtain first segment from gangue sorting section sieves material and pure thoroughly
Spoil；Therefrom coal sorting section obtains second segment and sieves material and middle coal thoroughly, and obtain third section from cleaned coal sorting section sieves material and row thoroughly
Material, and cleaned coal sorting section overflow is cleaned coal；
(4) first segment is sieved into material thoroughly and is incorporated to middle coal, or be sent to both heavy medium cyclone or smalls jigging machine
In any one sorted after further obtain cleaned coal and middle coal, by coal in gained be sent to separation of coarse slime machine carry out again
Rough coal and cleaned coal are obtained after sorting；
(5) second segment is sieved to material thoroughly, third section sieves material thoroughly and the merging of the discharge object of cleaned coal sorting section is sent to weight
Any one in medium cyclone or smalls jigging machine the two obtains cleaned coal and middle coal after being sorted, and coal in sorting gained is broken
It is sent to after broken after separation of coarse slime machine and further obtains cleaned coal and middle coal.
Using above-mentioned technical proposal, including following advantageous effect：Coal jigging system and method provided by the present invention, it is complete
It all can reach and (be even more than) effect identical with full weight media coal separation, medium consumption reduces by 70% or more compared with full weight media coal separation
Or not having to medium, power consumption reduces by 40% or more；Meanwhile overcome full jigging flow to difficult separation coal and to granularmetric composition thin and end
The big coal separating effect of coal content is poor, saturating sieve is serious, cleaned coal loses larger defect, also solves dense media+jigging flow
Production cost is high and middle coal or cleaned coal lose more serious problem.Coal jigging method provided by the present invention, it is convenient
Operation, improves clean coal yield on very significantly, is suitable for the sorting of various coal quality raw coal.
