Thickening method and thickening system of whole tailing material slurry paste
The invention discloses a thickening method and a thickening system of whole tailing material slurry paste, wherein the thickening method includes following steps: (1) feeding whole tailing material slurry into a cyclone machine to separate the whole tailing material slurry into crude granular mortar and fine granular mortar, wherein the crude granular mortar, at a bottom flow, is fed into a vibrating sieve while the fine granular mortar, at an over flow, is fed into a thickener; (2) in the vibrating sieve, vibrating the fine granular mortar to sieve the fine granular mortar and feeding the fine granular mortar into the thickener, wherein crude granules are discharged into a sand bin; (3) feeding an over flow in the cyclone machine into the thickener and feeding the bottom flow in the thickener into the sand bin; and (4) in the sand bin, mixing the crude granular mortar and the fine granular mortar to obtain the paste. The thickening system is composed of the cyclone machine, the vibrating sieve, the sand bin and the thickener, wherein a material slurry pipe is connected to input of the cyclone machine. Outputs of the cyclone machine include two groups, one is connected to the vibrating sieve and the other is connected to the thickener. The outputs of the vibrating sieve include two groups, one is connected to the thickener, and the other is connected to the tail sand bin. The output of the thickener is connected to the sand bin. In the invention, the tailing material slurry is separated into crude granular mortar and fine granular mortar and then is thickened, so that thickening concentration can reach 70-82%, which is higher than that of a deep-cone thickener and a sand bin by 2-5%. The tailing utilization rate is higher than 95%.
