As one of the important equipments for chemical beneficiation, the flotation machine often has the phenomenon of unstable foam in the tank during the flotation process. It is not a problem that the foam is too large or too much, that is, the foam is too small and too small.
Then the flotation machine is too large or too small in the tank during the flotation process. What is the cause?
First of all, we should first understand how the foam in the flotation tank is generated.
It is a foam formed by the application of external tools into the low-pressure air, just like the use of pipes to inflate the water to create bubbles.
However, the bubbles generated by the inflation are not unstable, and the amount is also uncertain, so there is a flotation agent such as a foaming agent, which can increase the bubbles and ensure the stability of the bubbles.
So, who is the mastermind who caused too many bubbles in the flotation cell? That is the foaming agent. Under normal circumstances, if the amount of foaming agent exceeds the standard, the foam in the flotation machine will be too much, too large, and sometimes even the foam will be too large to reflect on the surface. On the contrary, the amount of foaming agent is not enough, and the foam in the tank will be reduced. And become smaller.
Then, if the foam in the flotation machine is too large or too small, what effect does it have on flotation? If the foam is too large or too small, the impurities will be less, which will not achieve the expected flotation efficiency, not only affect the flotation effect, but also affect the final recovery rate, which is not worth the loss.
