(54) Improvements in or relating to a process and apparatus for spraying a powder with liquid


(57) The process includes entraining a powder having an average particle size in the range of 1 micron to 1.0 mm in air within a mixing vessel and spraying the entrained powder with a liquid within a spray zone in the mixing vessel. The process is used especially for a throughput rate in the range of 20 to 100 kg/ hour of powder. The apparatus for carrying out the process includes a mixing vessel (2) accommodating an axially aligned venturi device (22) and a spray nozzle (18). The mixing vessel (2) may be connected to a vibratory fluidized bed chamber (28) for collecting the sprayed powder.
