Floatation Machine

---

Yigong floatation machine consists of two series: XJK and SF floatation machine, it is mainly applicable for separating non-ferrous metal, black metal, noble metal, non-metal mineral, raw body and materials of chemical industry, which are subject to coarse separation, swept separation, fine separation and floatation, so the useful ore are reclaimed.

Working Theory of Floatation Machine

When the floatation machine works, the motor drives the impeller to revolve, so the centrifugal effect and negative pressure are produced. On one hand, ample air is absorbed and mixed with mineral slurry, on the other hand, the mixed mineral slurry is mingled with additive, meanwhile, the foams are thinning, the mineral is bounded with foams, and floats up to the surface of mineral slurry and the mineralized foam is formed. The liquid surface can be adjusted with the height of adjustment flashboard, so that the useful foams are scraped with squeegee.

Features of Floatation Machine

The floatation machine has the advantages of large air-absorption capacity and low energy consumption. Every cell owns three functions: air absorption, slurry absorption, and floatation separation, and the cells form a floatation separation loop by itself without any auxiliary equipment, and is allocated horizontally, which favors the change of flow. The circulation of mineral slurry is reasonable, and can avoid the disposition of coarse sand to the largest extent. There is self-control device on the surface of mineral slurry, so it is easy to adjust it. The impeller has backward-inclined upper and lower vanes, which produce upper and lower circulation of mineral slurrry respectively.
