Non-ferrous metal beneficiation equipment - flotation machine
Working principle of flotation machine: When the flotation machine is working, the impeller is driven by the motor to rotate, generating centrifugal force to form negative
pressure, on the one hand, sufficient air is sucked in to mix with the slurry, on the other hand, the slurry is stirred to mix with the medicine, and at the same time, the foam is
refined, so that the minerals are bonded to the foam, float to the surface of the slurry and then form mineralized foam. Adjust the gate height and control the liquid level so
that the useful foam is scraped out by the scraper.
The working steps of the flotation machine are as follows:
1. Crushing and grinding: First, the raw ore is crushed and ground to make its fineness suitable for flotation.
2. Adjusting reagents: Adding reagents such as regulators and collectors to the flotation tank to adjust the chemical properties of the slurry to improve the flotation performance of useful minerals.
3. Stirring and feeding: The stirring device fully mixes the slurry and air and feeds it into the flotation tank.
4. Generate bubbles: Bubbles are generated in the slurry by providing compressed air or other gases to the flotation tank. The generation of bubbles is usually achieved by gas dispersion devices or mechanical stirring.
5. Mineral adhesion: Useful mineral particles come into contact with bubbles and adhere to the surface of the bubbles. Useful minerals have poor adhesion and are easy to form buoyancy with bubbles, thus floating to the top of the flotation tank.
6. Settling waste rock: Due to their strong adhesion, waste rock particles cannot combine with bubbles and sink to the bottom of the flotation tank.
7. Collecting useful minerals: The floating useful mineral particles form scum, which can be collected through scum tanks or other collection devices.
8. Discharging waste rock: After the waste rock settles to the bottom of the flotation tank, it can be discharged through a mud discharge device or a waste rock tank.
