ZDF series impurity separator combines the functions of paper defibering and impurities separating. Working with a pulper (for high or low consistency，continuously or in batches)，impurity separator is used for separating the light and heavy impurities，and defibering the unpulped scraps of paper from the hydrapulper.

ZDF series impurity separator consists of vat, horizontal defibering impeller, drive unit, inlet and outlet piping, ect. The stock from the hydrapulper enters into the impurity separator tangentially. With the slices inside the separator, the heavy impurity settles down to the bottom, then the stock and light impurities enter the ciculation zone.The stock is suctioned axially and thrown out from the periphery of the impeller with high speed to from strong turbulence circulation.With innner friction of the stock, pumping function of the impeller and the friction between the impeller and the screen plate, accepts pass through the screen holes and the light impurities discharge at the light-impurities-outlet tangentially with adjusting the slice and the clearance between the impeller and the screen plate, the quality and throughput of the stock can be controlled. Impurity separator works together with the pupler in order to separate the light and heavy impurities from waster paper stock as well as to increase the capacity of pulper. Waste paper stock can be handled with coarse screening efficiently，which results in simplifying the process and saving power consumption.
This machines have characteristics of high textile fiber rate,and low processing costs. Mainly uses in chossing of coarse screening after the fiber separator,duplex fiber separator and the pressure screen, after separation arranges in the tailings not to contain the textile fiber, conforms to the enviornmental protection emission standard. This product is introduces by Austrain VOITH Corporation, after diligently, already voluntarity developed the manufacture in every way by our company, is in the manufacture domestically scrap paper pulping flow processe the tail thick liquid the ideal equipment.
