Patent ID: 8146847

Claim:
A powder based granules disintegrating and sizing device, comprising: a drive shaft that is inserted horizontally in a casing main body; a plurality of circular plates that are fixedly supported at intervals by the drive shaft; and a plurality of stators, each being arranged opposed to a circular plate surface at a circumferential edge portion of respective circular plates of the plurality of circular plates, each stator and respective circular plates of the plurality of circular plate including: each stator having a flat surface facing the circular plate surface, the flat surface of each stator having an inner stator flat surface and an outer stator flat surface relative to a center of the circular plate surface, a sizing gap being formed by an opening between the outer stator flat surface and the circular plate surface, the outer stator flat surface extending parallel to the circular plate surface, whereby powder based granules having a size less than a width of the sizing gap pass through the opening, the inner stator flat surface being inclined relative to the circular plate with a distance between the inner stator flat surface being wider near the center of the circular plate and becoming narrower toward the outer stator flat surface, the inner stator flat surface ending at the outer stator flat surface and forming a border therebetween, and the sizing gap beginning at the border and extending between the outer stator flat surface and the circular plate, whereby powder based granules having a size greater than the width of the sizing gap accumulate above the sizing gap for disintegration and sizing, wherein each stator stretches over the entire circumference of the respective circular plates, and raw material feeding ports are provided on a side wall in the vicinity of the drive shaft of the casing main body and on an upper circumferential wall of the casing main body located between adjacent circular plates of the plurality of circular plates.
