SF mechanical agitation flotation machine
SF mechanical agitation flotation machine
Advantages:
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:
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 (ie, the main and auxiliary blades) and is twisted to the periphery, so that a negative pressure region 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. The slurry extracted from the lower impeller chamber has a larger specific gravity than the three-phase mixture extracted from the upper blade, so that the centrifugal force is increased, the movement speed is attenuated slowly, and an additional driving force is generated for the three-phase mixture of the upper blade. The centrifugal force is increased, thereby increasing the degree of vacuum in the upper impeller chamber, and assisting the suction. 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.
