Abstract: The invention provides several improvements in feedwells, one of which being a feedwell comprising a mixing zone for dissipating the kinetic energy of a fluid comprising pulp, a settling zone for promoting flocculation of the pulp and at least one inclined deflecting element for at least partially separating the mixing zone from the settling zone. Other improvements include a shelf at least partially defining an inclined path for removing material from the shelf into a feedwell chamber; at least two outlets arranged in a substantially concentric relationship with respect to each other; a portion of a second conduit varies in its cross-sectional size and/or shape so as to connect a feed inlet to a first conduit; and a partition for partially separating an outer mixing zone and an inner settling zone.
