ABSTRACT:
Apparatus and a method for de-watering a bead suspension of fragile beads having a high water content suspended in a liquid includes a staging vat, a metering vat, and a de-watering vat. The application of pressurized gas to the staging vat causes the bead suspension to move up a central feed tube which extends from the staging vat to the metering vat. The bead suspension is gravity fed from the metering vat through a transfer pipe and into the de-watering vat. The bottom portion of the de-watering vat has both an inner wall and an outer wall wherein the upper portion of the inner wall has perforations and the bottom portion is solid. Upon entering the de-watering vat, the bead suspension pours a short distance onto an inverted spreader cone. The bead suspension flows down the spreader cone and pours over the edge of the cone toward the perforated upper portion of the inner wall. The liquid flows through the perforations of the upper inner wall to the outer wall, and the de-watered beads are deflected toward the apex of the conical solid bottom portion of the vat for further processing.
