Classification and optimization of Flotation machine

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

There are as many as dozens of flotation machine at home and abroad, the classification method is not consistent, mine flotation machine according to different work principleare divided into four types that include Mechanical flotation machine, inflatable agitated flotation machine, inflatable flotation machine, gas precipitation flotation machine.Here are the details:
Mechanical flotation machine
Aeration and mixing of the pulp are achieved by mechanical stirrer,which belongs to outside air self-priming flotation.Its inflatable mixer is similar with the pumping characteristics of the pump,so it can absorb air and pulp itself.
Its characteristics are:First, 18 to 20 guide vanes is installed on the cover.Second, the impeller, cover, vertical axis, the intake pipe, bearings, pulleys and other components assemble into a whole.Third, a circle of vertical fin plates are installed in around the trough to prevent a swirl of slurry.
Inflatable agitated flotation machine
Its characteristics are:1, the amount of inflation is easy to regulate separately; 2,decrease the abrasion of mechanical stirrer; 3, the opting indicator is better; 4,a lower consumption of power. 5, larger inflation; 6, a upwelling of slurry form.
inflatable flotation machine
Its characteristics are:1,without mechanical stirrer and transmission parts,its structure is simple,which makes maintenance and operation easily.2,the size of inflation bubble is adjust by the structure of inflator; 3, bubbles is mixed with the countercurrent pulp.
Gas precipitation flotation machine
Gas precipitation flotation machine is mainly used for mineral fine particle flotation and oily wastewater off of oil flotation.

The optimization method of flotation machine£º
No matter what kind of flotation machine, we shoud consider its efficiency in the process of producting, according to the customer feedback information and experience we summarize several methods to improve the efficiency of the flotation machine.By optimizing the influence of the main factors of flotation machine's the amount of inflation can improve the efficiency of the flotation machine to a certain extent :
1,The impeller and cover plate gap:the amount of inflation reduced, but the gap is too small, can cause the impeller and cover plate collision and friction, and make the amount of inflation decline. The gap is more appropriate for 5 ~ 8 mm.
2,The impeller RPM: in a certain range, the impeller rotational speed, the amount of inflation also big, but revs, impeller, power consumption, quick wear face is not stable. Pulp In addition, some brittle ore easy generation of mud cavitation phenomenon.
3,Into a pulp quantity: when into the center of the pulp impeller is the most appropriate, the largest amount inflation . But into the OARS, when large amount more than the impeller's production capacity, can jam the pulp, inspiratory difficulty, the amount of inflation of air cylinder decline. In addition, internal pulp circulation is big (that is, from the cycle of securing the hole to return to impeller in the cavity of the pulp), then the amount of inflation is big. But the power consumption will increase.
4,The upper part of the impeller pulp density: the value that is larger and the effect on the impeller is the static pressure also big, rotating impeller resistance increases, the amount of inflation smaller.
There is disparity between domestic mechanical manufacturing technology and the international, technical problems cannot be solved overnight, but as long as we never give up the steps of chasing, our technology willl catch up with or even lead the world.
