Abstract
Apparatus and a method for the selective conditioning, wetting and coating of particles with a selective wetting agent. The apparatus includes a horizontally extending surface capable of vibration which vibration induces uniform translatory movement along the surface to particles upon the surface. A vertically extending barrier is on the surface and extends across the surface and at right angle to the direction of movement of particles upon the surface. A means for spraying the selective wetting agent onto the particles as they move along the surface and before they reach the barrier is provided. Means for removing excess wetting agent are provided on the surface along the direction of movement of the particles after the barrier. A pool of the selective wetting agent forms behind the barrier upon the surface.
