AI Technical Summary
In the process of fine tailings flocculation, if the stirring speed is too fast, it will break the flocculent material at the bottom; if the speed is too slow, the mixing will be uneven. Existing technology is unable to solve this contradiction.
By combining a gas storage bladder and a compression ball, uniform mixing is achieved by impacting the liquid with gas, avoiding the breakage of flocs caused by high-speed stirring. The gas released by the gas storage bladder under the action of the compression ball impacts the liquid, improving the uniformity of mixing.
This method achieves uniform mixing of liquids during the flocculation process of fine tailings, avoids the breakage of flocs caused by high-speed stirring, and improves the mixing effect.
