Froth flotation machine introduction
Froth flotation machine is used for separating ferrous and non-ferrous metals. It can be also used for separation of non-metal materials such as coal fluorite and steatite.
The impeller rotates by triangle belt of the motor, with produces centrifugal function and causes negative pressure. 0n one hand it draws in enough air mixed with ore magma; On the other hand it agitates to mix ore magma with chemical medicines.
At the same time, it minifies bubbles so that minerals can stick above them. Float on the surface of magma, and form mineralized bubbles. The height of plate can be adjusted to control fluid level so that the available bubbles can be scrapped out by scrapers.
Features of Froth flotation machine
1. Froth flotation machine has the advantages of large air-absorption capacity and low energy consumption.
2. Every cell owns three functions: Air absorption, slurry absorption, and flotation separation, and the cells form a flotation separation loop by itself without any auxiliary equipment, and is allocated horizontally, which favors the change of flow.
3. 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.
4. The impeller has backward-inclined upper and lower vanes, which produce upper and lower circulation of mineral slurry respectively.
Froth flotation machine working priciple
When flotation machine works, slurry is inhaled from the bottom of the cell to the space between impellers. Meanwhile, the low-pressure air send by fan is sent to this area through the air distributor in the hollow shaft. After sufficient mixing, the slurry is pushed out by the impeller, and then goes to the whole cell. When the froth rises to the stable level, after the enrichment processing, froth overflows to the froth trough from the overflow weir. Another part of ore slurry flows to lower part of impeller for the re-mix with air. The remained slurry flows to the next cell until becomes tailing.
