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

FIELD: separating solids from solids.

SUBSTANCE: centrifugal air vibration concentrator comprises air system arranged coaxially inside a conical cap provided with conical space defined by its inner side and made of two coaxial truncated cones mounted with a spaced relation one with respect to the other and provided with vertical ribs on their outer side. The top section of the air system is provided with inlet branch pipe connected with the inner space through air ducts. The inner space of the air system is in communication with the inner space of the relief unit made of a ring-shaped chute with sloping bottom and provided with branch pipe for discharging light fraction. The section is provided with the shield from the side of the inner space and made of a branch pipe for discharging air. The hopper is made of a funnel coaxially mounted inside the air system and is provided with axial outlet that faces the disk secured to the bottom of the conical cap. The disk is provided with a rod made of a screw with tip pointed into the funnel. The periphery of the disk is provide with the conical shell. The vibration generator is made of a rotating eccentric member. The hollow shaft of the conical cap is in communication with the inner space of the cap.

EFFECT: enhanced efficiency.
