Abstract
The present invention comprises a control system and method for the continuous mixing of slurry while removing entrained bubbles. The control system for continuous mixing of slurry with removal of entrained bubbles comprises a power and fluid rate control, wherein the powder and fluid rate control is coupled to a mixer through a powder feeder and a liquid pump. A fluid level control is coupled to the mixer and a surge tank, and a flow rate is coupled to the surge tank. The present invention also comprises a method for controlling the continuous mixing of slurry while removing entrained bubbles comprising providing a powder and fluid rate control, wherein the powder feeder and fluid rate control is coupled to a mixer through a powder feeder and a liquid pump. A fluid level coniol is coupled to the mixer and a surge tank and flow rate control is coupled to the surge tank.
