PCT No. PCT/AT94/00069 Sec. 371 Date Feb. 15, 1996 Sec. 102(e) Date Feb. 15, 1996 PCT Filed May 18, 1994 PCT Pub. No. WO94/27713 PCT Pub. Date Dec. 8, 1994A mixer for fluffing and mixing pulp with treatment additives includes a disc rotor, an annular stator, a pulp feed channel, a ribbon feeder and a baffle, the axially rotating disc rotor including a shaft and a grinding segment. The stator includes a grinding segment which opposes the rotor grinding segment. The feed channel is coaxial with the rotor axis, has a discharge end which confronts the rotor and has an inlet end for receiving pulp. The ribbon feeder is coaxially disposed within the feed channel and has a hollow axially rotating shaft. This feeder discharges pulp at the rotor toward the mixing and fluffing zone. The baffle is carried on the feeder shaft and guides the pulp toward the fluffing and mixing zone. Treatment additives are introduced as the pulp moves toward the discharge end of the channel. |
