Abstract
A hydrocyclone is provided with a wear monitoring element of the type of a tube (24) or the like embedded in the wall section of the shell of the hydrocyclone. When the furrows worn by abrasive fraction of the cyclone are deep enough to reach the monitoring element, the wear causes a visually observed leak or some other signal alerting the operating personnel to the need of replacing the partly worn hydrocyclone.
