Flotation speed refers to the flotation time required to achieve a certain recovery rate (or flotation unit production capacity). Increasing the flotation recovery rate and shortening the flotation time, that is, increasing the flotation speed, is also an important issue in flotation production practice. The main measures that can be taken to increase the speed of flotation are: Black Cat,Black Cat Wear Parts,Diagram Loader Bucket Parts,Excavator Bucket Wear Plates JiLin LangYi Mechanical Equipment Company Ltd. , https://www.vxceo.com
1. Reasonable adjustment of the pharmaceutical system, especially the amount of foaming agent. In general, a slight increase in the amount of blowing agent will promote the flotation rate. However, care must be taken that excess foaming agent will reduce selectivity. Especially in the case of large selection of work and large amount of collector , it should be noted that the foaming agent should not be excessive.
2. The flotation speed increases within a certain range as the inflation amount of the flotation machine increases. Therefore, in an appropriate range, measures to increase the speed of the flotation machine impeller, reduce the depth of the groove, and reduce the gap between the impeller and the cover plate to increase the amount of inflation can increase the flotation speed.
3. Under the condition of ensuring the recovery rate, try to make the slurry pass through the flotation tank quickly, and the route of the slurry flowing through the flotation tank is changed from parallel to series, which is beneficial to the improvement of the flotation speed.
4. The size of the selection slot must be appropriate. Since the amount of slurry entering the selection tank is small and the time required for the selection is short, the size of the selection tank cannot be too large. The selection tank is too large, so that the slurry stays in the tank for too long, resulting in relatively depleted pulp grade in the tank, so that the bubbles can not be effectively mineralized, which not only depletes the concentrate foam, but also reduces the flotation speed.
5. Control the appropriate slurry concentration to get the maximum flotation speed. If the plasma concentration of low floating beneficiation, flotation rate and the maximum possible recovery will be reduced, this time to increase the collector dosage in order to ensure recovery. If the slurry is too concentrated, the flotation speed will be slower, so it is necessary to increase the flotation time to ensure a certain recovery rate.
It should be noted that increasing the flotation speed only means shortening the flotation time or increasing the recovery rate per unit time, which is only one aspect of the flotation index. On the other hand, the selectivity of flotation is to increase the quality of the concentrate and reduce the loss of useful minerals in the tailings. This requires a good understanding and control of the role of the prescription and various pharmaceutical agents and various technical operating conditions in order to get the best flotation results.
