PNEUMATIC FLOTATION MACHINE WITH JET AERATION ELEMENTS Russian patent published in 2018 - IPC B03D1/14 

FIELD: chemical industry.

SUBSTANCE: invention relates to the enrichment of mineral resources by the flotation method and can be used in the enrichment of ore and non-metallic raw materials, wastewater treatment, and in the chemical industry. Flotation machine includes a chamber, an air supply pipeline and a nozzle-equipped pulp feeding pipeline, arranged vertically and coaxially one in the other, an aerator, made in the form of a hollow chamber located under the pipelines and communicated with them, a bumper plate installed under the aerator, characterized in that the nozzle of the pulp feeding pipeline is cylindrically shaped with an outlet of smaller diameter to create an ejecting effect. Machine is equipped with nipples, connecting the aerator with a chamber volume, being installed at an angle of 120° and providing absorption and circulation of the pulp into the ejection effect zone for re-saturation with air. Cylindrically-shaped chamber is equipped with carousel-type foam removers.

EFFECT: technical result is an increase in the technological efficiency of the flotation machine.
