Suitable for the selection of non-ferrous metals, ferrous metals, and non-metallic minerals. SF flotation machine adopts a forward inclined tank body,dual-blade impeller, and is equipped with a guide pipe and a false bottom device (more than 10 cubic meters). The slurry in the tank carries out up and down double circulation according to the fixed flow mode, which is conducive to the suspension of coarse minerals. It can self-prime slurry and air, and does not need a froth pump. When the impeller rotates, the slurry in the upper and lower impeller chambers generates centrifugal force under the action of the upper and lower blades and is thrown around, creating negative pressure in the upper and lower impeller chambers. At the same time, the slurry in the upper part of the cover plate is sucked into the upper impeller chamber through the circulation hole on the cover plate, forming an upward circulation of the slurry; When the lower blade throws out the slurry in all directions, the lower slurry replenishes towards the center, thus forming a downward circulation of slurry; The air is sucked into the upper impeller cavity through the suction pipe and the central cylinder, and mixed with the sucked slurry to form a large number of small bubbles. After the flow is stabilized through the cover plate, it is evenly dispersed in the tank to form mineralized bubbles, which float up to the froth layer and scrape out by the scraper to become froth products.
