flotation machine with miing and aeration impeller

【Flotation machinestructure】The metallurgistflotationmainly made up of slurry tank, mixing device,aeration device, mineralized bubble discharging device and motor.【Flotation machineworking principle】Flotation process refers to theflotationseparation in mineral processing. In theflotation machine, the ore slurry treated with the added agent, byaerationand stir, some of the ore particles are …

Theair–coal attachmentis made stable by the addition of a frothing agent like pine oil. Successfulflotationis governed by different factors like oxidation and rank of coal,flotation reagents,agitation and aeration, particle size and pulp density,flotation machine, conditioning time, and pH of the pulp.

The conicaldisk impellersand wearing plates, as illustrated, are obtainable for all sizes ofmachines. Theconical disk impellersand wearing plates have been used in “Sub-A”Flotation Machinesfor many years but are rapidly being replaced by thereceded disk impellersand diffusers for general purposes.

The history offlotation machine designis essentially an account of the development of theimpeller-stator assembly, especially itsaeration capacity(Harris and Lepetic, 1966; Harris, 1974, 1976b). About a dozen designs are current throughout the world, while even more are obsolete.

Themechanical machineis dearly the most common type offlotation machinecurrently used in industry, followed by thecolumn machinewhich has recently experienced a rapid growth. Amechanical machineconsists of a mechanically drivenimpellerthat disperses air into the agitated pulp.

12.13.3 Reactor/SeparatorFlotation Machines. ... Conditioned feed pulp is mixed with air in an external self-aerationunit above theflotationcell. ... There is a necessity for the generation of three different hydrodynamic zones for effectiveflotation. The region near theimpellercomprises of a turbulent area required for solids suspension ...

Inflatable Flotation Machine.Inflatable flotation machineadopts mechanical agitation and press air from outside blend,impelleris used formixingslurry and dispersed bubbles, and required air is provided by external air blower. Mainly consisted of the cell body,impeller, cover plate, bell shaped, circular cylinder, spindle, central cylinder and cylinder, etc.

Formixingthe reagents with theflotationpulp, a tube 4| of smaller diameter than the tubular' drive'shaft 36 is inserted longitudinally and concentrically Within such shaft so as to terminate withinaeration impeller36 preferably just above chamber 38 thereof, as illustrated.

These factors, having different degrees of importance, are as follows: Type ofFroth Flotation MachineMesh analysis of the pulp Density of the pulp Reagents and pH Pulp temperature Conditioning Circulating load Contact periodAerationOf these factors influencing theflotationprocess, each has been given a great deal of consideration and ...

Allflotation cellshaving the same volume will have approximately the same capacity, with allowance made for horsepower, the efficiency of theimpeller and aeration. As theflotationcontact period is very important in anyFlotationCell, the actual cubical content of anymachineshould be carefully checked as well as accurate determinations ...

DR Flotation machinesoverview. The Metso DRflotation machineis the first mechanical open typemachineto incorporate a vertical circulation of pulp, made possible by combining a “recirculation well” with the distinctive top feedimpeller.

Flotation MachineWorking Principle. ... The slurry gasmixingflow is moved by theimpellerin a tangential direction, and then converted into a radial motion by the action of the stator, and uniformly distributed in theflotationtank. The mineralized bubbles rise to the foam layer, and the unilateral or bilateral scraping is the foam product

Mar 07, 1972· The particularflotation machineand system illustrated are presented preferred. However, other tank arrangements and other types ofaeration impellerand stator combinations can be utilized without departing from the broader inventive concepts.
