The flotation machine is applicable for the separation of nonferrous metal and ferrous metal. It is also used for separating nonmetal, such as fluorite and talcum.
1. The working principle of flotation machine is as follows.
The impellers are driven through V- belt transmission, which brings centrifugal effect to form the negative pressure. On the one hand, the flotation machine inhales sufficient air to mix with ore slurry; on the other hand it stirs ore slurry and mix with medication to form the mineralized froth. By adjusting the height of flashboard to control the liquid level and make the useful froth scraped by loam board.
2. The operating instruction of flotation machine
1) Check the bolts before starting the machine and use hand instead of the impellers to prevent the sediment from adding the burden of electromotor.
2) Adjust the height of the strobe carefully to keep the stabilization of liquid level and scrape the mineralized froth to the launder.
3) The impellers and stators should have a distance and should be changed when they are worn. The bearing in the pump should be maintained every three months.
4) After the maintenance of flotation machine, its commissioning should be pay great attention.
After the overhaul of the flotation machine, before the trial run, it is necessary to check and clean up the flotation cell carefully, then do the empty commissioning, and gradually add the fresh water to run the flotation machine. In the operation process, pay attention to adjust the size of the loop holes. At the same time, check whether there is a bias or impacting phenomenon on the impeller, and also pay attention to the operation sound of the flotation machine, ensuring various parts of the machine is normal. What’s more, in starting the motor, check the rotation direction of the motor shaft, and ensure that the impeller shaft rotates clockwise (look down to see).
