Knowledge of Classification and Optimization of Flotation Machine

Mine flotation machine according to different work principleare divided into four types that include Mechanical flotation machine, inflatable agitated flotation-cell, inflatable flotation machine, gas precipitation flotation machine.Here are the details: 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.No matter what kind of flotation-cell, 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, 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...
