Assortment and Adjustment of Flotation Machine
The characteristics of the physical gold beneficiation machine include the advanced separation efficiency and its enormous flexibility. The machine separates paramagnetic and low magnetic minerals of up to 3mm particle size in a wet separation process with magnetic field strengths of up to 15,000 Gauss. The main area of application of the impact crusher is the enrichment of hematite iron ores as well as the extraction of heavy mineral sands and the separation of impurities with throughput rates of between 6t/h and 200t/.
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. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery ,like cone crushers, Henan Hongxing is always doing the best in products and service.impact crusher for sale:http://www.hxjq-crusher.com/2.html
The optimization method of flotation machine:
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.
During the flotation process, pulp will be mixed with drug firstly and agitated. Then target ore grains will selectively attach to bubbles, float onto the surface of pulp, which will be scraped out and collected. And the rest materials will be left there. Thus, the result of separation is accomplished.
