A machine de flottation<\/strong> is the abbreviation of floating concentrator, referring to the flotation process equipment. The flotation machine is essential equipment in mineral processing, designed to separate valuable minerals from gangue through froth flotation. Here, we examine the three primary types: mechanical agitation, aerated agitation, and inflatable (column) flotation machines,<\/strong> highlighting their working principles and key characteristics.<\/p>\n

The aeration and agitation of the slurry are completed by the impeller and mechanical agitation device of the flotation machine. It belongs to the external gas self-priming flotation machine, generally the upper gas suction type, that is, air is inhaled near the mechanical stirring device in the lower part of the flotation tank.<\/p>\n

This kind of flotation machine can not only self-prime air, but also self-prime slurry. It is easy to realize self-flow when returning the ore middlings, has less auxiliary equipment, neat equipment configuration, simple operation and maintenance, etc. But this type of machine has small inflation and high power consumption.<\/p>\n

In summary, the mechanical agitating flotation machines are the most widely used flotation machine among all types.<\/strong><\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

As the impeller rotates, the slurry in the tank is sucked from the bottom of the tank through the lower end of the impeller to the impeller vane. At the same time, the low-pressure air fed by the blower enters the air distributor through the hollow shaft and the impeller.
\nUne fois que la boue et l'air sont bien m\u00e9lang\u00e9s entre les roues, ils sont expuls\u00e9s obliquement de la p\u00e9riph\u00e9rie de la moiti\u00e9 sup\u00e9rieure de la roue, et le stator est stabilis\u00e9 et orient\u00e9 pour p\u00e9n\u00e9trer dans l'ensemble de l'auge.
\nThe bubble rises to the foam stabilization zone. After the enrichment process, the foam overflows from the overflow weir and enters the foam tank. A part of the slurry flows to the lower part of the impeller, and then is stirred by the impeller to remix to form mineralized bubbles, and the remaining slurry flows to the next trough until it eventually becomes tailings.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n
