Abstract:
A method of granulating powder, said method comprising:mixing a powder of primary particles and a mist of binder by means of a fluidizing air flow in a main body container so as to form a mixture;collecting the mixture of the powder and the binder on a filter surface of a filter, which is disposed in a generally flat shape in such a way as to cover an inner circumferential face of the main body container, such that a powder layer of primary particles is formed on the filter surface;peeling the powder layer off from the filter surface so as to crush the powder layer into fragments;returning the fragments into the fluidizing air flow and mixing the fragments with the binder mist again; andrepeating the above steps until the binder is coated on all of the primary particles and a desired granule of coated primary particles is obtained.
