Abstract
Method and apparatus for coating particles, characterized in that to provide loose particles with a coating formed by a liquid, said method comprises the operations of forming a column-shaped layer of said particles, directing an air current upward through said layer, direction of a stream sprayed of said liquid upwards through said layer, one of said streams being of sufficient intensity to produce a vertical circulation of said layer; interruption of said liquid flow and continuation of said air flow after interrupting said liquid flow.
