Efforts to improve the flotation machine flotation speed


Flotation machine flotation speed refers to reach a certain recovery rate (or flotation machine unit production capacity), the flotation time required. Improve the flotation recovery rate and shorten the time, that is, improve the speed of flotation. The main measures of improve the flotation speed are:


1) the adjustment of reasonable prescription, special attention should be paid to the amount of blowing agent. Generally speaking, slightly increase some frother will promote floatation speed. But must pay attention to: excessive foaming agent will reduce the selectivity, so, when selected and collecting dose is larger, more should pay attention to the dosage of foaming agent don't too much.


2) in the appropriate range, increase flotator impeller speed, reduce the trough and depth, the impeller and the cover plate and narrow the gap to increase your measures, to promote floatation speed.


3) as soon as possible to make pulp by flotation cell. Series tank than parallel groove is fast, also can improve the speed of flotation.


4) the size of the selected tank must be appropriate. General said selected slot size not too big. Select trough is too big, make pulp in the tank to stay too long. Not only can make the foam concentrate dilution, and also reduce the speed flotation.


5) control appropriate pulp density, can obtain the biggest flotation speed.
