Abstract
A flow-through coil planet centrifuge having a hollow-walled, vertical-axis rotating bowl with a helically-coiled long separation column spirally contained in the hollow wall of the bowl. A stationary, vertical-axis drive motor is located in axial alignment with the bowl. The bowl is rotatably coaxially supported in a cage-like frame. The bowl is rotated by the motor via the frame by a system of belts and gearing which compensates for the rotation of the bowl and column relative to the motor and frame to avoid the twisting of the flow tubes of the column. The outer portion of the frame is provided with a vertical support tube for the flow tubes to prevent excessive strain on the tubes during high speed revolution of the frame.
