Abstract

The present invention relates to an apparatus for the uniform distribution of a small amount of liquid on bulk materials. The method is performed by spraying the liquid with at least one ultrasonic nozzle onto the bulk material, which is finely particulate. The spraying may occur before, during, or both before and during, mixing the particulate solid in a mixing apparatus. Dust may be significantly reduced by the apparatus of the instant invention, and the apparatus is useful for applying not only liquids, but emulsions, solutions, dispersions, or melts. The mixer may be mechanical or pneumatic.
