<p>PROBLEM TO BE SOLVED: To provide an improved pulverizer by which particles within a range of required size are obtained with high efficiency and a toner causing no problem of the image quality with respect to pulverizers by which material to be pulverized is pulverized between a rotor which is supported on a rotating shaft and on whose outer surface a lot of projected parts parallel to a generating line continue in the peripheral direction and a stator which has a minute gap outside the rotor and on whose inner surface a lot of projected parts parallel to a generating line continue in the peripheral direction. SOLUTION: Relating to a pulverizer by which material to be pulverized is pulverized between a rotor 1 which is supported on a rotating shaft and on whose outer surface a lot of projected parts in parallel to a generating line continue in the peripheral direction and a stator 1 which has a minute gap outside the rotor 1 and on whose inner surface a lot of projected parts in parallel to a generating line continue in the peripheral direction, the number of recessed parts of the rotor 1 is 0.9-2.0 times that of recessed parts of the stator 2.</p> |
