Abstract: In the light of the problems of large water flow, non-uniform and difficult separation of the coal slime in the underground working face of the coal mine, a concentrated type cyclone with a concentration hopper is studied, and the influence of the concentration-type cyclone on the solid performance of the concentrated cyclone is investigated. The results show that the best combination parameter is 0.14MPa, the diameter of the bottom flow port is 15mm, the diameter of the concentrated bucket is 21mm, the bottom flow concentration is 47.61%, and the bottom abortion rate is 42.19%. The best parameter is the feed pressure of 0.12 under the evaluation index of the bottom abortion rate. The bottom flow concentration is 40.52% and the bottom abortion rate is 46.78% in the MPa, bottom outlet diameter 18 mm, concentration bucket caliber 27 mm, mine water test. According to the dimensionless relationship, the industrial operation test of cyclone amplification is carried out. The swirl concentration equipment can effectively reduce the water content of mine water, and the concentration of slime can reach nearly 70%.
