Abstract

Hydrocyclone for dividing a substance mix into an acceptable fraction and a reject fraction containing dirt substances, the hydrocyclone including a separating chamber, which in part consists of a cylinder part, provided with at least one tangential feed connector for the substance mix and with a coaxial exit tube for the acceptable fraction, and which in part consists of a sorter cone on the extension of the cylinder part, having at its apex an exit aperture for the reject fraction. The shell or outer wall surface of the sorter cone has been provided with at least one recessed line or area extending over part or all of its length, whereby as the wall thickness of the sorter cone is substantially reduced from its original amount due to the wear caused by the reject fraction a perforation ensues in the recessed line or area, the leakage taking place therethrough being recovered in a closed chamber located outside the hydrocyclone and which has been formed by affixing to the margins of the recessed line or area a fluted strip with closed ends.
