Abstract
Pusher centrifuges having screen drums rotatable about axes of rotation are used for separating a mixture into solid cake and into liquid phase. Pusher centrifuges may further have pusher bases arranged in the screen drums and arranged to be movable to and fro alternately in a first pushing direction and a second pushing direction along the axis of rotation that are used in order for the solid cake to be alternately displaced along the axis of rotation. The mixture is introduced into a first empty space or into a second empty space using a feed device. The first empty space is established on a displacement of the solid cake by the pusher base in the first pushing direction and the second empty space is established on a displacement of the solid cake by the pusher base in the pushing direction opposite to the first pushing direction.
