ABSTRACT:
A chamber having a slurry-admitting inlet at one end has a metering opening lengthwise thereof for feeding slurry to an associated slurry processing machine. A rotatable bar, having a plurality of spaced apart grooves formed therein, is disposed in immediate proximity to the metering opening to control slurry-flow through the opening. The grooves insure that access to the opening, by the slurry, will be greater than the largest floc diameter of the pulp at all operating conditions.
