PNEUMATIC FLOTATION MACHINE Russian patent published in 2013 - IPC B03D1/24 

FIELD: process engineering.

SUBSTANCE: invention relates to concentration of minerals and may be used for processing mineral bearing ferrous, nonferrous, rare and noble metals and for cleaning effluents of solids and oil products. Pneumatic flotation machine comprises central pipe, aerator, T-joints, reactor, separation chamber, bells, foam settler, foam flute and tails discharge device. Flotation machine is equipped with flow distributor for demixing of aerated pulp in two flows containing, preferably, mineralized bubbles and pulp. This flow distributor is shaped to ring composed of a straight truncated cone. Bells are arranged tangentially at identical or different height in symmetry about vertical axis. Flow distributor bottom edge is connected with separator chamber top edge while top edge of said bells are connected with appropriate bottom edges of reactor pipes which increases flotation rate and reduces loss of mineralised bubbles with tail (chamber) product.

EFFECT: higher quality of flotation.
