An apparatus for mixing and spraying a slurry. The apparatus comprises a mixing chamber and a screw means, disposed within the chamber, for mixing and transporting material downstream to an air atomization nozzle. Another aspect of this invention is a method for mixing and spraying a slurry. The method comprises introducing and propelling a particulate solid along a mixing chamber. A liquid is introduced downstream from the introduction of the solid, a sufficient distance such that no substantial liquid backs up to the introduction of the solid. The solid and liquid are mixed to form a slurry, substantially in the absence of air. The slurry is propelled downstream, substantially in the absence of air, and atomized.
