Apparatus for granulating powder
 An apparatus for granulation of fine, light powder by mixing a powder and a mist of binder with a fluidizing air flow. The apparatus includes a container and a filter, provided along an inner peripheral surface of the container, for forming a high density powder layer thereon. A space, formed between the container and the filter, is divided into a plurality of ring-shaped zones. Also, a backwash mechanism and an exhaust mechanism are connected to the container so as to be selectively communicated with the ring-shaped zones.
