Process and device for separating solids from mud with screw presses

The separation and dewatering of solids from slimy liquids with separators, whose pressure is built with a screw, is disturbed by the high viscosity of the liquids; In order to enable separation and dewatering, vibrations are introduced into the filling space of the separator, the action of which continues into the entry area of ​​the screen basket, which causes a reduction in the viscosity of the slimy liquid and thus allows the gravity drainage required for the separation of the solids. For this purpose, a vibrator (4) is provided outside the filling space (2), the vibrations of which can be transmitted via supporting ribs (5) to a vibrator (6) arranged in the liquid,
