<p>CENTRIFUGAL SEPARATOR A centrifugal separator of the type comprising a bowl which is rotated about its axis and which has on the inner surface of the peripheral wall, a plurality of axially spaced radially extending rings and in between the rings, a plurality of openings through which water is injected from outside the bowl, has the openings arranged tangentially to the surface of the bowl and in a direction opposite to the direction of rotation to improve the fluidization of the material on the peripheral surface of the bowl. The openings are manufactured from a plurality of separate wall portions, each of which has projections stamped outwardly which are then drilled to provide tangentially extending holes. The wall portion is then rolled and assembled with a plurality of rings into a bowl where each wall portion is of greater diameter than the previous bowl portion closer to the base. An opening in the base lies under the lowermost ring and extends into a projection from the lowermost peripheral wall portion. A wear insert arrangement is positioned adjacent the open mouth of the bowl to receive material ejected from the end of the bowl.</p> |
