Coarse stock cleaning of low-density debris with fiber free rejects.
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 debris is removed through a continuous bleed. The system offers reliable operation with excellent rejects removal, creating high quality accepts as a result.
Energy efficient, applying power only where required
Reduced contaminant build-up for increased productivity
Traps heavy debris for periodic or continuous removal of rejects that are virtually fiber free
Built tough to withstand high volumes of debris
Optimally designed with very few moving parts
High removal of light contaminants such as plastics, polystyrene, and Styrofoam®
