Abstract
A conventional gas-sparged hydrocyclone, including a plug that cooperates with an interior surface of the hydrocyclone to adjust the size of an orifice defined adjacent the suspension outlet, is mechanically adjusted. The plug position is adjusted by a mechanical device from a position exteriorly of the hollow body while the hydrocyclone is running with suspension fed to its inlet, to effect direct linear movement of the plug with respect to the body interior surface. The mechanical elements include first and second pins and links within the hydrocyclone, a shaft having a drive portion extending exteriorly of the hydrocyclone, and a manually actuated link assembly or stepper motor for rotating the shaft. The manual actuator may be associated with an indexing arrangement to positively hold the plug at the position to which it has been adjusted.
