炼焦煤粗煤泥深度分选新工艺研究

ccording to the current problem that the teetered bed separator (TBS) often misplace the cleaned coal into the tailings, when the feeding particle size of coarse slime is wider. We put forward a new technology that can maximize the recovery of cleaned coal from the coarse slime: combined the advantage of TBS and screw separator, then use the flotation to float clean coal from the screw separator cleaned coal after grinding. The feasibility Experiments were taken on the coarse slime from Jin Neng plant of Da Wukou coal preparation plant, Experiments show that the new process can resolve the problems mentioned above effectively, and the recovery of the TBS tailings can be about 27.35%-34.21%, which will bring good economic benefits for coal preparation plant.
