Method and device for separating particles- and/or fluid suspensions with different specific weight, using a rotatable, powered cup shaped separation receptacle with a vertical axis and an inner wall. The substance to be separated is introduced centrally to a bottom area of the receptacle for distribution at the bottom area and a lower part of the wall, and wherein the receptacle is upwardly open, for moving the substance through a helical groove 20 in the inner wall of the separation receptacle. The separation receptacle 11 is rotated in an oscillating manner, with cyclical tangential acceleration and retardation. The groove 20 is preferably provided with transverse steps extending over a part or the total width of the sidewalls of the groove. |
