摘要
A method with which a flowable suspension is clarified of solids in a solid bowl screw centrifuge (1), the flowable suspension being separated into only a single liquid phase and only a single solid phase, using a solid bowl screw centrifuge (1) which has a drum (2) set in rotation and a screw (3) arranged in the drum (2) and rotating at a speed differential to the drum, the screw (3) used in any case over part of its axial extent having two radially offset helices ( 15, 16) has the same or different winding direction and / or different pitch, so that a radially outer first screw flight (13a) and a radially inner second screw flight (13b) are formed so that part of the suspension to be processed is formed when the drum ( 2) and the rotating screw (3) through the second spiral located radially further inside (16) or in the radially inner screw flight (13b) is conveyed in a different direction and / or with the same direction and / or different speed than another part of the suspension, which is located in the area of the radially further outward helix (15) or the radially outer worm thread (13a) is located.
