SF flotation machine

Product Introduction:The flotation machine drives the impeller to rotate by the electric motor V-belt drive, and generates centrifugal force to form a negative pressure. On the one hand, the air is mixed with the slurry, and on the other hand, the slurry is mixed with the med

Application:The rough selection, sweeping and selection of flotation operations in the concentrator can be widely used for the selection of non-ferrous metals, ferrous metals and non-metallic minerals.

Product Features

The impeller has a back-tilted double-sided blade, which can realize double circulation of slurry in the tank; The gap between the impeller and the cover plate is large, and the air intake is large; The impeller has a low peripheral speed and a long life of the consumable parts; Forward tilting trough, small dead angle, fast foam movement; Large inspiratory capacity and low energy consumption; The wearing parts have a long service life; Conducive to the flotation of coarse minerals; Mechanical agitation, self-priming, self-priming slurry

Working Principle

The working principle of the SF flotation machine, 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 twisted to the periphery, so that a negative pressure zone is formed 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 cavity through the circulation hole on the cover plate to form a slurry circulation. When the lower blade pulls out the slurry around, the lower slurry is replenished to the center, thus forming a lower circulation of the slurry. The air is sucked into the upper impeller chamber through the suction pipe and the central cylinder, and is mixed with the sucked slurry to form a large number of fine bubbles, which are uniformly dispersed in the groove through the cover plate to form mineralized bubbles. The mineralized bubbles float up to the foam layer and are scraped off by the scraper to form a foam product.
