Abstract: The disclosed device is directed towards a surge tank. The surge tank comprises a side wall including an interior surface. A bottom of tank is coupled to the side wall, wherein the side wall and the bottom of tank define an interior of the surge tank and an exterior of the surge tank. At least one inlet is configured to fluidly couple the exterior of the surge tank with the interior of the surge tank. A weir is fluidly coupled to the inlet at the interior of the surge tank. A flexible element is coupled to the weir proximate to the bottom of tank. An outlet is defined in the bottom of tank.

Abstract: The disclosed system comprises an apparatus and a method continuously removing air from a mixture of ground polyurethane particles and a polyol liquid. The apparatus for continuously removing air from a mixture of ground polyurethane particles and a polyol liquid comprises a deaerator having an inlet to receive a mixture of liquid and fine particles and an outlet to disperse the mixture.

Abstract: 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 one 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 a 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.

Abstract: The disclosed device is directed towards a mixer apparatus comprising a barrel defining an interior and an exterior. The barrel has a first end and a second end opposite thereof. The barrel defines at least one inlet proximate to the first end and an outlet proximate to the second end. A motor unit is in operative communication with the barrel. A moving element is disposed in the interior of the barrel. The moving element is configured to move material through the barrel to the outlet of the barrel. At least one first mixing element is fluidly coupled to the outlet.

Abstract: The present invention comprises a control system and a 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 powder 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 control is coupled to the surge tank.
