The working principle and property of Flotation Machine

Release date : 2014-05-14      Source : Hongji Group

working principle:
when
flotation machine works, slurry is inhaled from the bottom of the trough 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 trough. 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_mis with air. The remained slurry flows to the next trough until becomes residue.
properties:


Condsidering the working principle of flotation machine and its particularity of using, flotation machine has some properties:
1ӢGood pneumatic
   Flotation machine must ensure that a sufficient amount of air inhaled pulp (some flotation machine is pressed into the outside air pressure fan) and try to diffuse throughout the tank. Because the more detailed the more uniform dispersion of air, mineral particles in contact with the gas full opportunity to the more efficient flotation the rates also higher.
2Ӣmixing
   Flotation confidential to ensure good mixing of the role of pulp, so that precipitation of mineral particles in suspension Buzhi Yu and can be evenly distributed in the tank, while promoting the dissolution of some insoluble pharmaceutical, pharmaceutical and mineral particles in order to facilitate a full role .
3Ӣcirculation of
   Within the pulp in the flotation of mineral particles can increase circulation opportunities for contact with the bubbles
4Ӣcan adjust the slurry surface and sustainability work
In the flotation process, sometimes need to adjust the thickness of foam and hold slurry flow. And in production from the feeding of the ore to the concentrate floating  till discharge, which is continuous process. According to its performance, flotation machines have the following basic components:
(1)tank,it has a row of holes into the ore slurry holes, and adjust the mineral surface of the gate device;
(2)inflatable device;
(3)mixing device;
(4)mineral foam discharge devices.
