Description
Technical field
The present invention relates to a kind of coarse slime gravity separation apparatus and method for, especially uses and belong to coal separation technical field
The coarse slime gravity separation apparatus and method for used.
Background technique
In the technical process of entire coal separation, the granularity of coarse slime is between dense medium separation lower limit and flotation upper limit week
(2-0.3mm) is enclosed, is all difficult to carry out high-precision sorting to coarse slime using dense medium sorting and flotation.So coarse slime is generally independent
Sorting, assorting room equally have conclusive linking effect on entire coal separation process procedure, separating effect
Quality is directly related to the efficiency of dense medium sorting and slime water treatment link.Major diameter dense medium cyclone and the processing of fine beans
The extensive application of equipment is also reduced to a certain extent between gravity treatment and coal while improving product quality and separating effect
The separating effect of coarse slime near Slurry treatment granularity boundary.Separation of coarse slime problem, which becomes, influences most domestic coal preparation plant essence
The main bottleneck that coal yield improves.
Development gravity separation of coarse slime equipment in recent years has some new equipment applications, although slime separation technology is not
Disconnected progress, novel device continuously emerges, but there are still some limitations when handling coarse slime for some equipment.It is closed by Stokes
It is theoretical in decline of the ore particle in the density field of centrifugal force it is found that the centrifugal force and grain diameter that particle is subject in cyclone at
Direct ratio, therefore the material of+3mm or more in infall process, biggish particle diameter can increase centrifugal force suffered by ore particle and
Speed is efficiently separated, material is pressed into Density Separation, the common cyclone of the material of+0.3mm can solve.For -0.5mm coal
Mud medicament Preferential adsorption and there is stronger selectivity, the coal slime flotation of this part can solve preferably.
Existing separation of coarse slime equipment is widely used, such as hindered bed separator (TBS), spiral, coal
Mud dense medium cyclone etc., but its there is also more or less disadvantages during fine coal, constrain mentioning for sharpness of separation
It is high.Spiral parameter itself is not easy to adjust that the variation of feed property, separating density is higher, is enriched with to ore particle on chip to adapt to
Effect is poor, and liquid-solid fluid bed separation machine is relatively narrow to the particle size range requirement of pan feeding, separating density is lower, and Slime dense medium cyclone needs
It individually to set up a set of fine media circulation and recovery system, system design complex, special particulate dielectric film filter difficulty, production
It is at high cost.
