A GRAVITATIONAL CONCENTRATOR Russian patent published in 2005 - IPC

FIELD: mining and metallurgy industries; production of gravitational concentrators and concentration of minerals for metallurgy.

SUBSTANCE: the invention presents a gravitational concentrator and is dealt with the field of mining industry, mainly with concentrating of minerals and with metallurgy for final treatment of rough concentrates of metals. The gravitational concentrator includes a cone-shaped chamber, a device for a source material feeding into the chamber, a container for periodical release of the concentrate by batches. The chamber is inverted with its vertex of a cone downwards. The device for a material feeding is made in the form of a hollow shaft with a release window located inside the chamber. The hollow shaft is supplied with a ripping device. The ripping device is made with a capability of rotation in the form of needles as an evolvent. The chamber is supplied with the ring-type receivers with connecting pipes and the control gates for ensuring a uniform distribution of water in different cross-sections in height of the cone. The surface of the cone is perforated. The concentrator contains no less than three chambers with a common drive for simultaneous separation of fine-bored grades of the source material. The technical result is an increased efficiency of separation of particles by their density.

EFFECT: the invention ensures an increased efficiency of separation of particles by their density.
