FLOTATION MACHINE ROTOR Russian patent published in 2017 - IPC B03D1/16 

FIELD: machine engineering.

SUBSTANCE: group of inventions relates to devices used for mixing the slurry located in flotation machines. They can be used to extract particles of material, such as ores, minerals, metals or other material contained within the solid substance being in suspension in a liquid slurry or pulp. The flotation machine has at least one flotation cell, each of which comprises a reservoir large enough to accommodate slurry containing liquid mixed with at least one solid material; and a rotor disposed in the reservoir with possibility of rotation to stir the slurry, contributing to the bubbles formation. The rotor includes a body having an inner channel and a lower opening; several inner blades attached to the body and positioned therein adjacent to the inner channel. The inner blades at least partially form several connecting channels inside the body connected to the inner channel and each of which is formed within the body, extending from the inlet, mating with an internal channel inside the body to the outlet at the outer surface of the body, so providing the passage of slurry drawn into the lower opening as a result of rotor rotation, along its inner channel and extrusion from the outer body surface through the connecting channels at locations above the lower opening. Also, the rotor comprises several outer blades attached to the body so that they rotate during body rotation located above the lower opening and extending outwardly from the outer body surface and from the outlets of the connecting channels. The housing also includes passageways separated from the connecting channels. Each of the passageways has an inlet for receiving at least one gas and an outlet for discharging at least one gas incoming through the inlet. Each outlet of each passageway is located at a distance from other outlets and other passageways in the body located between the immediately adjacent outer blades.

EFFECT: increased minerals extraction.
