Mixing apparatus and method
First Claim
1. A device comprising a duct open at a first end, a solid inlet for feeding particulate solids entrained in a stream of gas centrally into the duct at or near its second end with a direction of flow generally towards the first end, a plurality of sprays arranged around said solid inlet for spraying liquid into the duct as a spray of mist particles that substantially fills the width of the duct and that travels generally towards the first end and means for injecting said solids through said solids inlet into the duct with a swirling action.

Abstract
A method and apparatus for dispersing a particulate solid uniformly in a liquid are described. The apparatus comprises a duct open at one end with a central inlet at the other end through which the solids are fed entrained in a stream of gas, and a plurality of liquid sprays arranged around this inlet. The particles are wetted as they travel through the duct by the mist particles generated by the sprays and they emerge from the open end of the duct and pass into the liquid in which they are to be dispersed.

- 8. A method of distributing particulate solids in a liquid uniformly, which method comprises using an apparatus comprising a duct open at a first end, a solid inlet for feeding said particulate solids entrained in a stream of gas centrally into said duct at or near its second end with the direction of flow generally towards said first end, and a plurality of sprays disposed around said solid inlet for spraying liquid into said duct as a spray of mist particles that substantially fills the width of said duct and travels generally towards said first end, said duct being mounted over a vessel containing said liquid, said method further comprising at least partially filling said vessel with said liquid, wetting said particulate solids with the same or a compatible liquid by feeding said particulate solids through said solid inlet and through said duct and allowing the wetted particulate solids to pass directly into said vessel.
