Flotator applicable to the separation of non-ferrous metals, ferrous metals, precious metals, non-metallic mineral and chemical rough pieces and raw materials, after roughing, sweep the election, selection and anti-flotation homework. Recovery of useful minerals. Inspiratory capacity, low power consumption. Both inspiratory each slot, suction slurry and flotation triple function, self-flotation circuit, without any auxiliary machine tool equipment, the level of configuration, ease of flow changes. Pulp cycle reasonably can to minimize the coarse sand sediments. Pulp with the noodle-controlled device to regulate the Convenience. Impeller with backward-style upper and lower leaves. Slurry produced on the leaves on the cycle, the next cycle of leaf pulp produced. Triangle-generation transmission from motor Driven impeller rotation, the centrifugal effect arising from the formation of negative pressure, on the one hand, inhalation of air and pulp adequate mixing, on the one hand, mixing the pulp with the drug mixture, at the same time refining the bubble, so that mineral foam adhesive above the float to the pulp re-formation of mineralized foam noodle. Flashboard height adjustment, control surface, so that the bubble be useful scraper scraped off.
