Abstract

The present invention is directed towards a method of preventing fine particles, especially liming material, from becoming air borne, and the addition of desirable chemical compounds to the particles. The method comprises feeding fine particles of solid to an enclosed inclined chute and locating at least a first inclined shelf and a subsequent inclined shelf within the chute, each shelf having an inclined top surface, a bottom surface and a leading edge. At least one liquid fog nozzle is located between the bottom surface of the first shelf and the chute, the fog nozzle creating a fog of liquid in the direction of the leading edge of the first shelf. Once the particles fall from the shelf, a fog is applied to the particles as the vertical free flow of particles falls from the leading edge of the first shelf. The inclined positioning of the chute allows gravity to pull the once coated particles to at least a second inclined shelf. After passing over at least the second shelf, the liquid coated particles are discharged through a discharge funnel, the liquid coating preventing fine particles from becoming air borne.
