Abstract
A method and apparatus for treatment of recycled fiber material and/or of the reject fraction discharged from paper mill screening systems of the short circulation of a paper machine, recover fillers as completely as possible and return the fillers back to the process as efficiently and economically as possible. The loss of fiber/mineral discharge as mill rejects from vortex cleaning and filler manufacture is decreased by treating a concentrated mineral fraction of the rejects to disperse the filler-mineral fraction and return the filler back to the paper making process.
