Pusher Centrifuge - LP

In the pusher centrifuge the transport speed of the solids,sliding over the wedge wire basket,is lower than in the worm/screen centrifuge. Consequently the retention time of the material to be centrifuged in the basket is longer.The pusher centrifuge is especially suitable for separation of abrasive *** addition the relatively thick,dense filter cake ensures a good yield of the very fine solids.Both criteria long retention time and dense filter cake will give the possibility of economical additional dewatering of pre-dewatered solids with high content of fines coming from all kind of filters.Our pusher centrifuges are executed with 1-and-2-step rotating parts. In most applications the outer basket will be cylindrical-conical. In the conical part of the outer basket the filter cake will loosen itself because it adjusts itself all the time on a different diameter to make the discharge of the capillary liquid easier.
An additional advantage is a reduction of the pushing energy for the transport of the solids.
Single-step pusher centrifuges are the most economic solution for simple separation, which means separation of coarse crystal solids from a slurry with high solid concentration.
The most frequently used execution is the double-step.Double-step pusher centrifuges are for a more universal application than a single-step pusher because of the shorter steps.Variable solid concentration and/or finer particles in the feed can be handled easier.Additionally intensive washing of the product cake with washing liquid,displacing the mother liquid, can be realized much easier.
