The flotation equipment is mainly a flotation machine and other equipment for implementing the flotation process. The slurry is stirred and aerated. Under the action of various flotation agents, the ore particles adhere to the bubbles, the bubbles rise, form a mineralized foam layer, and are scraped or overflowed by the scraper. This series of flotation processes are all in the flotation machine. Completed in the middle. The flotation machine is mostly made up of multiple tanks connected in series.
According to the method of mixing and aeration, different flotation machines can be divided into five types:
(1) Mechanical agitation type. There are centrifugal impellers, and some are star-shaped rotors and rod-shaped rotors. The agitator rotates at high speed in the flotation tank to drive the slurry to flow and generate negative pressure in the impeller chamber to absorb air.
(2) Inflatable mechanical stirring type. In addition to mechanical agitation, the flotation tank is filled with low-pressure air.
(3) Inflatable type. It is stirred by air and generates bubbles, such as a flotation column and a foam separation device.
(4) Gas precipitation type. Using the method of reducing pressure or first pressing to reduce the pressure to atmospheric pressure, the dissolved air in the slurry is precipitated to form microbubbles.
(5) Pressure dissolved gas type. The charged air is pre-dissolved in water by high pressure, and then precipitated in a flotation cell under normal pressure to form a large amount of microbubbles.
Currently, the most commonly used gold beneficiation plant flotation machine is our domestic mechanical flotation machine.
Wire Cage Welding and Forming Machine
The Spun Pile cage forming welding machine is a fully automatic professional equipment for producing reinforced steel cage of concrete spun piles. The welding strength of the whole equipment is small, the forming is fast, the structure is reasonable, the maintenance is simple. Combined with modern frequency conversion control and man-machine interface, it is effective to ensure the stable and reliable quality of the steel cage.
