Flotation Machine refers to the completion of the flotation process machinery and equipment. In the flotation machine, after adding the pharmaceutical treatment of the pulp, aerated by stirring, so that some of the mineral particles selectively fixed on the bubble above; floating to the surface of the slurry was scraped to form a foam product, the rest remain in the pulp In order to achieve the purpose of separation of minerals. Flotation machine structure in many forms, the most commonly used is a mechanical agitation flotation machine.
Flotation machine principle is driven by the motor with a belt drive impeller rotation, resulting in the formation of negative pressure centrifugal, on the one hand inhalation of sufficient air and pulp mixing, on the one hand mixing slurry and drug mixing, while the thinning of the foam, the mineral bonding foam Above, float to the mineral surface and then form a mineralized foam. Adjust the ram height to control the fluid level so that the useful foam is scraped off by the scraper.
After the slime and the medicament are fully mixed, they are fed into the bottom of the first chamber of the flotation machine. After the impeller rotates, a negative pressure is formed in the wheel cavity so that the pulp under the tank and the pulp in the tank respectively enter from the lower suction mouth and the upper suction mouth of the impeller The mixing zone also allows air to enter the mixing zone along the gas guide sleeve where the slurry, air and medicament mix. Under the centrifugal force of the impeller, the mixed pulp enters into the mineralized zone, the air forms bubbles and is crushed, fully contacts with the coal particles to form mineralized bubbles, uniformly distributed in the tank body under the action of the stator and the turbulence plate Section, and move up into the separation zone, the enrichment of the formation of foam layer, the bubble squeeze out the body to form a clean coal foam.
Flotation machine is mainly used for sorting of non-ferrous metals such as copper, zinc, lead, nickel, gold, can also be used for roughing and selection of ferrous and non-ferrous metals. Mechanical agitation flotation machine Pulping aeration and agitation by the impeller and the composition of the mechanical mixing device to complete, are external air flotation machine, these are flotation machine. It is an essential equipment for a beneficiation production line.
