Pulp Line Machine Impurity Separator

Impurity Separator

lmpurity separator combines the functions of paper defibering and impurities separating. It's equipped with a pulper (for high or low consistency, continuously or batch-wise), impurity separator is used for separating the light and heavy impurities, and defibering the stock from the hydrapulper.

Design Features

1. Impurity separator consists of steel housing,horizontal defibering impeller, drive, inlet and outlet piping, etc.

2. The stock from the hydrapulper enters into the impurity separator tangentially. With the weir inside the separator, the heavy impurity settles down to the bottom, then the stock and light impurities enter 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. With inner 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. 

3. With adjusting the weir and the clearance between the impeller and the screen plate, the quality and throughput of the stock can be controlled.

4. Impurity separator works together with the pulper in order to separate the light and heavy impurities of waste paper stock as well as to increase the capacity of the pulper.

5. Waste paper stock can be handled with coarse screening efficiently, which results in simplifying the process and saving power consumption.
