ABSTRACT:
There is obtained with greater efficiency a powder coating having an average particle diameter smaller and a particle size distribution range narrower than those currently made by conventional methods. The method to obtain the powder coating comprising; introducing a solid mixture of coating materials between a rotor and a stator; the rotor being supported in such a manner as to be rotating round the shaft center and, on its periphery, being arranged with multiple convex lines extending in a direction of the shaft and being lined up along the periphery; the stator having a cylindric rotor-opposite face arranged with a certain interspace between this face and the rotor periphery and having, on the rotor-opposite face, multiple convex lines extending in the direction of the shaft and being lined up along the circumference, wherein the rotor-opposite face is arranged in such a manner as to be capable of opening in order to expose the rotor periphery; and then pulverizing finer said mixture by said rotating rotor and said stator.
