A 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 grinder segment, which opposes the rotor-grinding segment. The feed channel is co-axial with the rotor axis, and has a discharge end, which confronts they rotor and has an inlet end for receiving pulp. The ribbon feeder is co-axially disposed within the feed channel, and includes a hollow axially rotating shaft. The feeder discharges pulp at the rotor towards 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.
