Abstract

See full text

The twin pusher centrifuge contains a sieve or filter drum having discharge openings at both of its ends. At the center of the sieve or filter drum there is arranged an inclined pusher or thrust floor member. This pusher floor member rotates at a rotational speed differing from the rotational speed of the sieve or filter drum. Consequently, the pusher floor member performs a wobbling or wobble movement between two extreme positions. Due to the wobbling or wobble movement the centrifuged product is pushed towards the two ends of the sieve or filter drum. The product infeed opens within a central aperture formed in the pusher floor member, whereby the product is uniformly infed on both sides of the pusher floor member. The product infeed occurs either in a continuous or periodic fashion. In this manner an energy-saving jerk-free operation of the centrifuge is achieved using a particularly simple construction. By appropriately selecting the parameters such construction of centrifuge can be used for processing a broader spectrum of products.
