Model: SF-16 Effective volume: 16 (m3) capacity :6-16 (m3/min) Impeller diameter: 850 (mm) impeller rotation: 180 (r / min) Motor power stirring: 45 (kw) Motor power scraper: 3 (kw) 2 tank Weight: 15.3 (t) SF flotation machine has the following characteristics: 1, inspiratory capacity, low power consumption. 2, each slot both suction, suction slurry and flotation triple features, since as flotation circuit, without any auxiliary equipment, the level of configuration, ease of process changes. 3, slurry circulation reasonable, to minimize sand sedimentation. 4, with the pulp side of the controlled device, easy to adjust. 5, the impeller with backward curved blades up and down. Leaves on the pulp cycle, the next leaves the pulp cycle. SF flotation machine works: after mixing slime and potions to the first chamber into the flotation machine slot beneath the impeller rotation, a negative pressure in the wheel cavity, making the slurry tank bottom and tank respectively Under the impeller and the suction mouthpiece into the mixing zone, but also makes the air along the guide sleeve gas into the mixing zone, pulp, air and medicament mixed here. The centrifugal force of the impeller, the mixed slurry into the mineralized area was pulverized to form bubbles of air, full contact with the coal particles, the formation of mineralized bubbles and turbulence in the stator plate under the action of evenly distributed in the tank section, and moved upward into the separation zone, rich foam layer is formed by scraping the bubble discharge mechanism, the formation of coal bubble. Bottom above the mineralized coal particles will not loop through the suction hole and mix again, mineralization and separation. Impeller tank bottom is not part of the pulp, the pulp through buried in the mine in the box below into the second chamber groove to complete the whole process of the first chamber, into the third chamber, so the cycle flotation machine, slurry through the last one room after the final tailings discharged into the tailings box.
