Method of granulating powder and apparatus for it
 The present invention is intended for granulation of powder comprising the steps of mixing a powder and a mist of binder by fluidizing air flow, collecting the mixture of the powder and the binder on a filter surface thereby forming a powder layer thereon, peeling off the powder layer from the filter surface thereby crushing the powder layer into pieces, returning the crushed fragments into the fluidizing air flow and mixing them with the mist of binder again, repeating the steps until the desired granule is obtained.
