The Float Purger Stock Cleaning System operates on the primary screen reject flow in the coarse screening loop of any long fiber furnish that is heavily contained. This field proven machine incorporates three basic functions:
1. Concentration of light contaminants.
The action of the bottom rotor sets up a strong vortex forcing light contaminants to the center of the air core. The reverse dish at the top of the unit insures that the contaminants are removed at the lowest pressure point, providing high removal efficiency.
2. Defibering of undeflaked stock.
A defibering action occurs between the bottom rotor and the extraction plate. The accepted pulp usually is returned to the pulper tub.
3. Collection and removal of heavy grit.
Centrifugal force pushes heavy contaminants into a tapered reject channel around the periphery of the extraction plate. This debris is removed through a continuous bleed.
