Abstract:
1. A powder based granules disintegrating and sizing device, comprising: a drive shaft which is provided in a horizontal direction inside a casing; a rotor which is fixed to the drive shaft; a sizing stator which is provided so as to oppose a plate surface of a circumferential edge portion of the rotor and has an inclined surface which reduces a gap with respect to the plate surface of the rotor toward the circumferential edge thereof; and a gap section where the powder based granules settles being formed by the plate surface of the rotor and the inclined surface of the sizing stator, and a disintegrating and sizing section being formed by a narrowest gap section between the circumferential edge of the rotor and the sizing stator, wherein the drive shaft is supported in a cantilever fashion, the rotor is fixed to an open side end portion thereof, the sizing stator is installed over the whole circumference of the rotor, a raw material supply port is opened in the vicinity of the central portion of the rotor, and a product output port is opened in the vicinity of a position directly below the rotor, wherein a cutaway section is formed in the circumferential edge of the rotor on the front side thereof, and a sizing ring is installed in the cutaway section, and wherein two types of sizing stator are provided, one having a flat sizing surface and one having a sizing surface formed with projecting portions, and three types of sizing ring are provided, one having a flat sizing surface, one having a sizing surface formed with grooves and one having a sizing surface formed with projecting portions, the sizing stator and the sizing ring being installed on the front cover and the rotor respectively, in accordance with the properties of the powder based granules which is subjected to sizing processing.
