"GRAN-M" PLANETARY CLASSIFICATION ENRICHMENT DEVICE Russian patent published in 2017 - IPC B03B5/32 

FIELD: mining engineering.

SUBSTANCE: planetary classification device for enrichment and transportation of minerals due to the action of centrifugal force fields includes a body, consisting of a unitary hopper, a flattened cone scrubber, overlapped by an conical collecting pipe, ejected snails for the removal of small and coarse fractions, mounted on one side on the frame by Hooke's joint bearings, and on the other side to the drive shaft with a flywheel that informs the body the planetary-translational motion on the circular cone. The device is equipped with a separator in the form of a flattened cone with crimps, a snail for the withdrawal of the separator concentrate and sprinklers. The body is hingedly connected to the pin, which is rigidly fixed in the groove on the spoke of the flywheel, with the possibility of moving the pin attachment point in the groove, made in the form of an arc, each point of which is equidistant from the point of intersection of the device axes.

EFFECT: increasing the extraction efficiency of fine fraction minerals into the concentrate.
