ABSTRACT:
The twin pusher centrifuge comprises a sieve or filter drum having discharge openings on both sides thereof. At the center of the sieve or filter drum there is provided a pusher rotating at a rotational speed which differs from the rotational speed of the sieve or filter drum. The pusher contains pushing surfaces which are inclined at an angle relative to the direction of product movement. Product infeed pipes open to the rear of the pushing surfaces. These pushing surfaces are alternatingly positioned at opposite inclinations or comprise two pushing surfaces directed at opposite inclinations with respect to one another. Due to such an arrangement the product which is infed to the center of the sieve or filter drum is pushed from such center or central region of the drum towards both sides thereof in the direction of the discharge openings. An energy-saving and jerk-free operation of the centrifuge is thus obtained while employing a particularly simple construction of centrifuge.
