Flotation machine classification
Types of mechanical flotation machine flotation machine, inflatable flotation machine, flotation machine or hybrid inflatable flotation machine, gas precipitation flotation machine.Mechanical flotation machineMechanical flotation machine and stirring the pulp of the inflatable are achieved by a mechanical agitator, air flotation machine is outside theSelf-priming flotation machines, pneumatic stirrer suction pump with similar characteristics, both air and self-absorption self absorption slurry.Mechanical flotation machine (commonly known as type A) which is characterized by:First, the cover is installed on the guide vanes 18 to 20.Second, the impeller, cover, vertical axis, the intake pipe, bearings, pulleys and other assembled - a whole part.Third, the trough installed in a circle around the vertical fin plate to prevent the pulp produced vortex.
Inflatable agitated flotation machineIts characteristics are:
1, inflated the amount of easy to separate regulation;
2, mechanical stirrer wear small;
3, the sorting index is better;
4, power consumption low.
Inflatable flotation machineInflatable flotation machine:
1, structural features: no mechanical stirrer is no transmission components;
2, inflatable features: inflatable device, the bubble size by the inflator restructuring; 3, bubbles mixed with the slurry characteristics: upstream mixed.
Uses: treatment composed of simple, high-grade, easy to choose ore sweep the election.
Flotation Machine Features
Flotation device has the following characteristics: low power consumption. Each slot both suction, suction slurry and flotation triple function, since as flotation circuit, without any auxiliary machine tools, the level of configuration, ease of process changes. Pulp cycle is reasonable, to minimize sand sedimentation. Cycle on the leaves in the pulp, the pulp produced under the leaves under the cycle.
Flotation machine working principle
Sorting machine is mainly used for flotation of copper, zinc, lead, nickel, gold and other non-ferrous metals, ferrous metals and can also be used for the roughing and selected non-metallic. Sorting machine driven by the impeller rotation V-belt drive motor, a centrifugal role in the formation of negative pressure, on the one hand inhalation of pulp mixed with sufficient air, mixing the pulp with the drug combination on the one hand, and refined bubble, the bubble on top of mineral bond, floating to the surface and then form a slurry bubble mineralization. Ram height adjustment, control surface, so that was useful for foam scraper scraped off.Slurry after mixing for pharmaceutical and flotation of the first chamber into the slot beneath the impeller rotation, a negative pressure in the wheel cavity, making the tank bottom and slot in the next slurry by the impeller and the suction into the suction mixing zone, the gas also makes the air along the guide sleeve into the mixing zone, pulp, air and mixed pharmaceutical here.In the impeller centrifugal force, a mixture of pulp into the mineralized zone, the formation of air bubbles and was crushed, and full access to coal particles, the formation of mineralized bubbles and turbulence in the stator plate under the action of uniformly distributed in the tank section, and move up into the separation zone, rich foam layer formed by the discharge body blow bubbles, the formation of coal bubble.Sorting swivel slow rotation, when the sorting room into the floating market area, this time selected by the slurry distributor of materials to six points, respectively, to the choice of site, the weak magnetic mineral particles being sucked in the tooth plate and with the sorting ring rotation. Non-magnetic mineral particles in the gravity and effect of pulp flow through the gap tooth plate, into the lower part of the tailings sorting ring slot. Go to the ore separation room cleaning position, a small amount of wash water to enter, the inclusion of the gangue, even with the body wash into the tailings and sludge tank (the machine is not set in the mine shafts) to concentrate to improve the quality of purposes. When the sorting room to the location of the magnetic field is weak (the concentrate rinse area), is injected into the pressure of water, will suck in the teeth of a weak magnetic board mineral particles into the concentrate tank.
Mineralization above the bottom of the coal particles will not cycle through the suction hole and once again mixed, mineralization and separation. Impeller tank bottom is not part of the pulp, the pulp through a buried mine in the box under the slot into the second chamber, the first room to complete the whole process, the third room, flotation machine again and again, the pulp through the last tailings discharged into the tank room final tailings.

Flotation machine Description
Floating concentrator flotation machine is short. In the flotation machine, pharmaceutical treatment by adding the slurry, by stirring inflation, which some mineral particles to selectively fixed in the bubble above; float to the surface to be scraped off a bubble slurry product, the rest remain in the pulp, in order to achieve the purpose of separation of minerals. Flotation structure in many forms, most commonly used mechanical flotation machine.
