With the improvement of coal mining mechanization, the yield of the foam coal is increased, secondary foam coal is generated through crushing and other processes in the coal washing process, and a large amount of coarse clean coal with the granularity of 0.09-2mm is difficult to recover and is lost in coal slime due to the limitation of the existing reselection and jigging washing technologies. At present, the coal slime is mixed into clean coal for sale, so that the ash content of the clean coal is increased, and the coal dressing process becomes meaningless; or the coal is directly transported to a power plant for power generation, or is stacked in the open air or buried in place, thereby not only polluting the atmosphere and the ecological environment, but also wasting the coal resources.

The effect of separating high-ash coarse coal slime with ash content of more than 50% is worse, and qualified clean coal with ash content of less than 10% cannot be separated at one time; the spiral separator is suitable for separating low-ash, easy-to-separate and medium-grade coal, has separation density of more than 1.6kg/L and has poor separation effect lower than the numerical value, and cannot separate clean coal with ash content of less than 10% at one time due to poor coal separation effect when the coarse coal slime which is difficult to separate and recovers more than 50%.

Step 6: the coarse middlings and the clean middlings overflowed into the second jigging chamber 1-2 are continuously separated, and the middlings with large density sink to the second jigging chamber 1-2 stainless steel sieve plate 2 along with the pulse water flow under the action of the set pulse water flow and are discharged through the sieve of the second jigging chamber 1-2 stainless steel sieve plate 2. Under the action of pulse water flow, the clean coal with low relative density floats upwards and overflows to obtain the clean coal.
And (3) dehydrating the coal gangue and the middlings discharged by the sieve through a dehydrating sieve of a lower rectangular cone hopper 10 to obtain the gangue and the middlings.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention. In addition, the technical solutions between the various examples of the present invention can be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or can not be realized, the combination of the technical solutions should be considered to be absent, and is not within the protection scope of the present invention.
