Flotation is the separation of suspended solids from a liquid. The finest air bubbles that are produced attach themselves to the
solids and carry them to the water surface. Because of its high separation efficiency and extensive concentration, the flotation
process has many advantages over sedimentation.
Working principle of flotation machine:
The impellers are driven through V-belt transmission, which brings centrifugal effect to form the negative pressure. On the one
hand, the flotation machine inhales sufficient air to mix with ore slurry; on the other hand it stirs ore slurry and mix with medication
to form the mineralized froth. To adjust the height of flashboard to control the liquid level and make the useful froth scraped by
loam board.
The ore will be ground in grinding or after grinding of pharmaceutical water and the need to tune into a stirred tank by the pulp
after the pulp into the mixing tank to start the pulp into the air, to the formation of a large number of bubbles, some can not easily
be water wet, that is generally known as hydrophobic mineral particles attached to bubbles, and together with the bubbles
floating to the surface of the pulp to form a bubble layer mineralization, while others easily wet by water, that is generally known
as the mineral hydrophilic particles not attached to the bubble, but remain in the slurry will contain specific minerals in
mineralized bubble waiting vehicle, so as to achieve the purpose of dressing.
Usage of flotation machine:
To check the bolts before starting the machine and to use hand instead of impellers to prevent the sediment from adding the
burden of electromotor. To adjust the height of strobe carefully to keep the stabilization of liquid level and scrape the mineralized
froth to the launder. The impellers and stators should have a distance and should be changed when they are worn. The bearing
in the pump should be maintained every three months.
Features of flotation machine:
1. Large air-absorption capacity
2. Low energy consumption
3. 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.
4. The circulation of mineral slurry is reasonable, and can avoid the disposition of coarse sand to the largest extent.
5. There is self-control device on the surface of mineral slurry, so it is easy to adjust it.
6. The impeller has backward-inclined upper and lower vanes, which produce upper and lower circulation of mineral slurry respectively.
