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 ().
