Design Features:
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.
