<p>PCT No. PCT/FI94/00086 Sec. 371 Date Jan. 24, 1996 Sec. 102(e) Date Jan. 24, 1996 PCT Filed Mar. 10, 1994 PCT Pub. No. WO95/04189 PCT Pub. Date Feb. 9, 1995Recycled fiber pulp from a vortex cleaning plant (e.g. connected to the short circulation of a paper machine) effects the recovery and return of fillers in the recycled fiber pulp discharged from the vortex cleaning plant, in an efficient and economical manner. The loss of filler in the recycled fiber pulp discharged from the vortex cleaning plant is decreased by treating a concentrated fraction of the rejects from the vortex cleaning plant with a mixer/disperser for dispersing the filler in the recycled fiber pulp, and returning as much usable filler as possible back to the process.</p> |
