It is an inflatable and mechanical agitation type flotation cell,the. it can be applied to rougher, scavenger stage in the large or medium sized dressing plant, and can pick out non-ferrous metal, ferrous metal and nonmetallic minerals.

During the operation it need to be equipped with the blower and the wind pressure≥19.8 Kpa, KYF type flotation cell having no slurry absorption function, JPF type flotation cell having the slurry absorption function. So that when KYF type flotation machine is used alone it should come with the ladder configuration, the middling products return through foam pump.
