The flotation machine, also called flotation separator, flotation concentrator or flotation cell, is used for the separation of the nonferrous black metal as well as the separation of the non-metallic materials such as the coal fluorite and the talc. The impeller of the flotation machine is driven by the transmission spinning of the engine triangle to form the centrifugal formation and produce the negative pressure.
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. 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.
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. 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.
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.
