Impurity separator combines the functions of fiber disintegration and impurities separating into one. It is installed after pulper and used for separating light and heavy impurities, and disintegrates the stock that the hydrapulper hasn’t pulped.
It consists of steel housing, horizontal defibering impeller, drive, inlet and outlet pipe, etc.
With the weir plate inside the separator, the heavy impurities settle down to the bottom, then the stock and the light impurities enter into the circulation zone. The stock is suctioned axially and thrown out from the periphery of the impeller with high-speed to form strong turbulence circulation.
The quality and the throughput of the stock can be controlled by adjusting the weir and the clearance between the impeller and the screen plate.
Impurity separator works together with the pulper in order to separate the light and heavy impurities from waste paper stock, as well as to increase the capability of the pulper.
Waste paper stock can be handled with coarse screening efficiently, which results in simplifying the process and saving power consumption.

The capacity may be different according to different pulp variety and concentration.
So the capacity in the above chart is only used for choosing the model.
