ABSTRACT:
Hydrocyclone for dividing a fibre suspension into a lighter acceptable fraction containing fibres and a heavier reject fraction containing dirt substances. The hydrocyclone comprising a separation chamber consisting in part of a cylinder part provided with at least one passage for the tangential input of the fibre suspension to be divided into different fractions and having within itself a coaxially disposed tube for removal of the lighter fraction, and in part of a sorter cone on the extension of said cylinder part and on the apex of which has been adjoined a conical nozzle which has been made more abruptly tapering than the cone part and which at its apex has a removal aperture for the heavier fraction. On the inner surface of the sorter cone and conical nozzle has been disposed at least one guide vane running in the axial direction of the cyclone and which imparts to the heavier fraction, travelling along a spiral path on the inner surface of the sorter cone and of the conical nozzle, a radially inwardly directed component of motion. The guide vane common to both the sorter cone and the conical nozzle is located at their point of juncture.
