The Float Purger system is a vertical pressurized machine which performs three main functions to treat coarse screen rejects through a continuous pulping system. First, the bottom rotor creates a strong vortex forcing light contaminants to the center of the air core while the reverse dish at the top ensures contaminants are removed at the lowest pressure point. Second, a defibering action occurs between the bottom rotor and the extraction plate. The accepted pulp usually is returned to the pulper. Lastly, centrifugal force pushes heavy contaminants into a tapered reject channel around the periphery of the extraction plate. The system offers reliable operation with excellent rejects removal, creating high quality accepts as a result.
