Flotation machine applicable to ferrous and non-ferrous metal, can also be used for non metal such as fluorite, talc. The flotation machine by the motor triangle generation transmission driven rotating impeller, centrifugal action to form negative pressure, on the one hand inhalation of sufficient air and slurry mixing, on the one hand mixing pulp mixed with the drug, and refine the bubble mineral adhesive foam on top and float to the pulp surface and formation of mineralized bubbles. Adjust the height of the gate, liquid level control, make useful foam scraper scraping.
Working principle of flotation machine:
Flotation machine is mainly used for concentration of copper, zinc, lead, nickel, gold and other non-ferrous metals can also be used for ferrous metals and non-metallic rough election and selection. Selection machine is composed of motor triangle belt transmission drives the impeller to rotate, produces centrifugal force to form negative pressure, on the one hand inhalation sufficient air and ore pulp mixing, on the one hand mixing pulp mixed with the drug, and refine the bubble mineral adhesive foam on top and float to the pulp surface and formation of mineralized bubbles. Adjust the height of the gate, liquid level control, make useful foam scraper scraping.

Slime and reagent mix to into the first chamber of the flotation machine of a groove under, impeller rotation, in the round cavity negative pressure is formed, makes the pulp tank bottom and tank respectively by the impeller suction and suction into the mixing zone, also makes the air along the air guide sleeve into the mixing area, slurry, air and pharmacy here mixed.

Under the effect of impeller of centrifugal force, the mixed slurry into mineralized zone, air bubble formation and crushed, in full contact with the coal particle, formation of mineralized bubbles, in stator and turbulent plate, evenly distribution in cross-section groove, and to move into the separation region, rich set form a foam layer, discharged from the scraping mechanism, forming foam of float coal.
Separating ring slow rotation, when the separation chamber into the floating zone, the selected materials by slurry distributor respectively to the 6 separation point, weakly magnetic mineral particles are sucked in the tooth plate and with the separationring. Non magnetic particles in slurry flow under the action of gravity and through the gap tooth plate, the tailing tank platoon in the lower part of the separating ring. The separation chamber to middling cleaning position, a small amount of clean water to enter, the inclusion gangue, intergrowth and mud washed into the tailing tank (the machine is not set, middling groove) in order to improve the concentrate quality. When the sorting room to the field is weak position (concentrate Irrigation District, water injection pressure), will suck in the tooth plate on the weakly magnetic mineral particles into the concentrate tank. Then the separation chamberto another opposite polarity magnetic field, the separating ring rotates a circle, wherein each of the sorting room so repeated 6 times.
At the bottom of the groove above is not mineralized coal particles through the circular hole and the upper ceiling export mix again, mineralization and separation. Under the groove is not suction impeller of pulp, by buried in the pulp of the middling box into slots of the second chamber below to complete the first chamber of the whole process, into the third ventricle, flotation machine, so the cycle, pulp by the last room backward into the tailing box is used for discharging the final tailings.
Flotation process flow of flotation machine:
In the flotation process, the ups and downs of the mineral almost has nothing to do with mineral density. For example, pyrite and quartz, the population density of the former 4.2. The latter was 2.*8, but heavy mineral chalcopyrite float easily, quartz will sink at the bottom. The study found that the mineral can float with the water affinity size related, general and water affinity of large, easily water wettability of mineral, is hard to adhere to the bubbles to float. And the water affinity of small, can not easily be water wettability of mineral, easy to float.

Flotation and other mineral processing methods, to do a good job before the election of the material preparation, that is, ore to go through grinding classification, to achieve the appropriate concentration of the flotation fineness.
