The invention provides several improvements in feedwells, one of which being a feedwell (100) comprising a mixing zone (49) for dissipating the kinetic energy of a fluid comprising pulp, a settling zone (50) for promoting flocculation of the pulp and at least one inclined deflecting element (101) for at least partially separating the mixing zone from the settling zone. Other improvements include a shelf (3) at least partially defining an inclined path (4) for removing material from the shelf into a feedwell chamber; at least two outlets (111, 112) arranged in a substantially concentric relationship with respect to each other; a portion (123) of a second conduit (121) varies in its cross-sectional size and/or shape so as to connect a feed inlet (110) to a first conduit (120); and a partition (133) for partially separating an outer mixing zone (131) and an inner settling zone (132).
A feedwell for a separation device, the 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 a plurality of inclined deflecting element for at least partially separating the mixing zone from the settling zone, wherein each inclined deflecting element has an inner end and an outer end with respect to the feedwell, wherein one of the inner and outer ends is raised relative to the other of the inner and outer ends.
A method of separating pulp from a fluid, the method comprising the steps of:
