MECHANICAL FLOTATION MACHINE Russian patent published in 2005 - IPC

FIELD: mining industry; metallurgy; food and other industries.

SUBSTANCE: the invention concerns to the devices for a flotation of materials and may be used in mining, metallurgical, food and other industries. The technical result is decreased power input at maintaining a high quality of dispersion, and increased productivity of the machine. The flotation machine contains a chamber and an aeration unit consisting of a stator and an impeller mounted in respect to each other with an axial and a radial clearance. In the upper part of the impeller on blades there is a ring-type element, the width of which is more than 1/2 lengths of a blade of an impeller. The internal diameter of the ring is equal to the diameter, which forms an internal butt surface of a blade of the impeller, and above the ring-type element there is the circulation pipe.

EFFECT: the invention ensures a decrease of power input at maintaining a high quality of dispersion, increased productivity of the machine.
