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 that has at least on inlet for receiving the fine particles and liquid and an outlet. The mixer further comprises a barrel that has an inlet for accepting the fine particles and an outlet for dispersing the fine particles and tank for holding the liquid. The tank has a top surface in which the barrel is disposed such that the outlet of the barrel is disposed under the surface of the liquid. An inlet of a vacuum centrifuge is coupled to the outlet of the mixer to receive a mixture of liquid and fine particles. A surge tank is coupled to an outlet of the vacuum centrifuge, wherein the mixture is dispersed from an outlet of the surge tank.
