<p>In a pulp thickener with a conical base 10 topped by a cylinder 11, pulp is fed through pipe 20 to an inverted conical baffle 19 where the velocity of flow of the pulp is dissipated. In addition gasses are vented from the feed through pipe 17 so that flocs do not float due to adherent bubbles. In other embodiments the feed is kept constant by recirculating clear liquid.</p> |
