The flotation machine at home and abroad as many as dozens of the classification method is also inconsistent, mining flotation machine according to the different works are divided into: mechanical flotation machine, inflatable flotation machine, hybrid flotation machine or inflatable flotation machine, gas precipitation flotation machine.

Whatever kind flotation machine, in production, must take into account its efficiency, Fortune machine based on customer feedback and lessons learned for improving their own flotation efficiency. Inflatable flotation machine by optimizing the amount of the main factors to a certain extent, improve the flotation efficiency:

1. Impeller and cover the gap: the gap is large, the aeration rate decreases, but the gap is too small, will cause the impeller and cover the impact and friction occurs, and to decline in inflation. More appropriate for the gap is 5 to 8 mm.

2. Impeller rotation: in a certain range, the impeller speed is large, the large inflatable volume, but the speed is too large, the impeller wear faster, power consumption and large, the slurry surface unstable. In addition, some of the ore is brittle is easy to produce the phenomenon of mud.

3. Into the plasma volume: when the impeller center into the most appropriate amount of slurry, then the largest inflatable. But the paddle into the excessive, when the production capacity over the impeller, the slurry will plug the air tube, breathing difficulties, decline in inflation. In addition, the internal loop volume of slurry (ie, the loop holes from the cover to return to the pulp cavity volume of the impeller), the inflated volume. But the power consumption increases.

4. Impeller upper slurry concentration: the larger the value, the effect of static pressure on the impeller are also great, the impeller rotation resistance increases, inflation quantitative small.
