Abstract:Research and design a 45 m3 mechanical flotation machine in order to achieve a large-scale,high efficiency,energy conservation flotation machine.Describe the structure and operating principle of the flotation machine,focus on the structural design of the tank impel-ler,stator,scraping bubble agencies,steady flow plates in the flotation machine.The performance test by water flotation machine show that, when the impeller speed is 137.58 m/s,immersion depth is 895 mm,the flotation machine has a optimal process indicators.The application of 45 m3 mechanical flotation machine in Dayangquan coal preparation plant shows that,the ash of clean coal is 10. 69%,the ash of tailings is 55.35%,the yield of clean coal is 68.03%.The flotation machine has good recovery effects on different size fractions slime.Compared with FCMC3000 flotation column,in the case of the feed ash has a little difference,the tailings ash,coal yield,combustible body recovery, improve index of the XJM-S45 flotation machine flotation increased by 18.61%,18.84%,23.90%,18.30%.
