Due to the influence of certain factors, the flotation process is drastically changed, resulting in abnormal foam layer thickness and foam scraping amount. It can show two extreme phenomena: one is that the surface of the ore falls, and the foam is not scratched at all; the other is a large amount of slurry and foam overflow, which is called “ running †. The reason for the former case is that the fineness of the grinding is too coarse, the amount of treatment suddenly increases, the mass fraction of the flotation is too large, the amount of the foaming agent is insufficient, or the nature of the ore is changed. Measures such as adjusting the grinding and grading operation, reducing the amount of ore added water, appropriately increasing the amount of foaming agent, and adjusting the pharmaceutical system may be adopted. The latter case is caused by a decrease in the amount of treatment, a decrease in the flotation mass fraction, an increase in the amount of additional water, an increase in the amount of circulation, an increase in the flotation agent or an increase in the slime in the ore, and leakage of lubricating oil into the slurry. Treatment measures such as water volume, reduction of medium ore volume, reduction of drugs or withdrawal of drugs.
When this situation occurs urgently, a large adjustment can be temporarily made by adjusting the gate. Then, the real cause of the abnormality should be analyzed immediately, and the solution is fundamentally adjusted.Check valves are "automatic" valves that open with forward flow and close with reverse flow. The pressure of the fluid passing through a system opens the Valve, while any reversal of flow will close the valve. Our range included swing check valves, wafer check valves.
Swing check valves come with resilient seats. Installed in pumping applications to prevent back flow they can be used for drinking water as well as waste water. The disc is connected to the shaft via a flexible bush that allows disc and valve seat to adjust exactly. All interior parts are ductile iron coated with drinking water approved epoxy or EPDM.
