Abstract: In a decanter centrifuge a bowl is provided and rotates in use around a horizontal axis of rotation, a base plate provided at one longitudinal end of said bowl, the base plate having an internal side and an external side, an outlet opening provided in said base plate, the outlet opening extending through a first angular interval relative to the axis of rotation, and a wall projecting from the external side of said base plate, wherein the wall extends from the vicinity of the outlet opening towards a rim of the base plate, the wall extending through a second angular interval, the second angular interval being at least 30°, and the wall having in a radial plane perpendicular to the axis of rotation an inclination relative to the radial direction of at least 60°.

Abstract: The invention is a decanter centrifuge for separating a first substance and a second substance with different densities, comprising a bowl rotating in use around a horizontal axis of rotation in a direction of rotation, said axis of rotation extending in a longitudinal direction of said bowl, a radial direction extending perpendicular to the longitudinal direction, a base plate provided at one longitudinal end of said bowl, said base plate having an internal side and an external side, an outlet opening provided in said base plate for discharge of one of said substances. A slide valve body is adapted for covering an adjustable part of the outlet opening to delimit an effective area of the outlet opening.
