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.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. Operating instruction: To check the bolts before starting the machine and to use hand instead of impellers to prevent the sediment from adding the burden of electromotor. To adjust the height of strobe carefully to keep the stabilization of liquid level and scrape the mineralized froth to the launder. 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. The flotation column at work, the slurry by adding a strong mixing of the flotation reagent into the column from the center of its feeder. Due to the gravity of the slurry from the column slowly decline. After a pneumatic device, compressed air dispersion into a large number of tiny bubbles, evenly distributed in the entire cross section of the column and slowly rising. Slurry bubble formation convection. In this case, the floatability of minerals attached to bubbles and float to the slurry above the formation of mineralized bubbles from the bubble flow tank to overflow or scraper will be scraped off the foam, is concentrate. Another part does not float the gangue can not be attached to the bubbles on the discharge from the tailings to enhance device or go to the next job processing is tailings. Raw material mill:As a piece of Ore separating line equipment,Raw material mill is widely used in beneficiation, building material and chemical industries. Raw...
