How to increase the amount of aeration of the mechanical agitation flotation machine?

Both practice and theoretical research have proved that within a certain range, increasing the amount of aeration can greatly improve the production capacity of the flotation machine and improve the flotation index. There are many factors affecting the aeration volume of the flotation machine, which can be adjusted mainly from the following aspects:

(1) The gap between the impeller and the cover. The size of this gap directly affects the amount of inflation. If the clearance is too large, the slurry will turn from the front side of the blade to the back side of the blade, reducing the vacuum behind the blade and reducing the amount of inflation. If the clearance is too small, the impeller and the cover are prone to impact. And friction, and reduce the amount of inflation. Tests have shown that a suitable gap is 6 to 8 mm.

(2) The speed of the impeller. The larger the rotational speed of the impeller in a certain range, the larger the amount of inflation. However, if the rotational speed is too large, the impeller cover wears quickly, the power consumption increases, and the slurry surface is unstable.

(3) The pulp mass fraction also has a great influence on the amount of aeration and the degree of dispersion. In a catastrophic condition, as the mass fraction of the pulp increases within a certain limit, the amount of aeration and the degree of dispersion also increase. However, the mass score should not be too large. If it is too large, the amount of inflation will deteriorate.
