PROCESS AND APPARATUS FOR CONTINUOUS MIXING OF SLURRY WITH REMOVAL OF ENTRAINED BUBBLES

摘要

The present system comprises an apparatus and a process for continuously dispersing fine particles in a liquid. The apparatus comprises a mixer (200) that has at least one inlet (251) for receiving the fine particles and liquid and an outlet (254). The mixer further comprises a barrel (201) that has an inlet for accepting the fine particles and an outlet for dispersing the fine particles and a tank (250) for holding the liquid. The tank (250) has a top surface in which the barrel is disposed such that the outlet of the barrel (201) is disposed under the surface of the liquid. An inlet of a vacuum centrifuge (300) is coupled to the outlet (254) of the mixer (200) to receive a mixture of liquid and fine particles. A surge tank (400) is coupled to an outlet of the vacuum centrifuge (300), wherein the mixture is dispersed from an outlet of the surge tank.
