Abstract:
1. A double pusher centrifuge including a screen drum rotatable about an axis of rotation for separating a mixture into a solid material cake and a liquid phase, a mixture distributor arranged in the screen drum and having a pusher base device, which is arranged to be movable to and fro along the axis of rotation, so that the solid material cake is alternately displaceable with an outer ring zone, and with an infeed device with which the mixture can be introduced via the mixture distributor into an empty space, which arises adjacent to the outer ring zone on displacement of the solid material cake by the pusher base device, the pusher base device having acceleration surfaces on both sides, which are inclined at a pre-determinable angle of inclination with reference to the radial direction, so that the mixture introduced by the infeed device can be accelerated to a pre-determinable peripheral speed before reaching the screen drum, and wherein the infeed device includes an inlet funnel for pre-acceleration of the mixture which extends at a substantially constant opening angle conically diverging in the direction towards the pusher base device.
