CENTRIFUGAL AIR VIBRATION CONCENTRATOR Russian patent published in 2007 - IPC B07B7/08 

FIELD: separation solids from solids.

SUBSTANCE: centrifugal air vibration concentrator comprises air system arrange coaxially to the inner conical cap with conical space and to its inner side made of two coaxially arranged truncated cones with a spaced relation to each other and provided with vertical ribs on their outer side. The top section of the air section is provided with inlet branch pipe connected with its inner space through air ducts. The inner space of the air system is in communication with the inner space of the relief unit through the conical space. The relief unit is made of a ring-shaped chute provided with the sloping bottom and the branch pipe for light fraction in its bottom section. The top part of the unit is shielded from the inner side by means of the branch pipe for discharging air. The hopper is made of a funnel mounted coaxially to the air system and has axial outlet in the bottom part that faces the disk mounted with a spaced relation.

EFFECT: enhanced efficiency.
