PNEUMATIC FLOTATION MACHINE AND METHOD OF FLOTATION Russian patent published in 2014 - IPC B03D1/24 

FIELD: process engineering.

SUBSTANCE: set of inventions relates to flotation performed using the air driven flotation machines and can be used for dressing of minerals with low or average content of valuable component. Proposed machine for flotation of particles from suspension to obtain foam product comprises housing with flotation chamber, at least one system of nozzles to feed gas and suspension in flotation chamber and at least one gassing system to feed extra gas to flotation chamber. Said gassing system is arranged inside flotation chamber and under said system of nozzles. At least one trammel of gassing system inside flotation system. Besides, it incorporates at least one measuring device to analyse formed foam product and/or suspension and at least one computer connected with said measuring device. At least one computer is configured to calculate and output adjustment variable in response to data from measuring device to vary the position of said gassing system by at least one said trammel.

EFFECT: higher efficiency of separation and yield of flotation product.
