分级装置、分级方法、调色剂和制造所述调色剂的方法
摘要：
本发明涉及分级装置、分级方法、调色剂和制造所述调色剂的方法。所述分级装置包括圆筒形外壳，粉末材料进料口，配置在所述外壳中与所述粉末材料进料口在水平方向上连接的百叶窗环，中心芯，分离器芯，由所述中心芯和所述外壳的内壁在粉末材料进料侧处界定的分散腔，由所述中心芯、所述分离器芯和所述外壳的侧内壁界定的分级腔，和环绕所述百叶窗环的流动通道，其中在所述分级装置的包含所述粉末材料进料口和所述百叶窗环的部件的水平横截面中，所述百叶窗环位于其中该百叶窗环未横穿百叶窗环侧的所述粉末材料进料口的壁表面延长线的位置上。
摘要（英）：

A classifying apparatus including a cylindrical casing, a powder material feeding port, a louver ring disposed in the casing to be in communication with the powder material feeding port in a horizontal direction, a center core, a separator core, a dispersion chamber defined by the center core and an inner wall of the casing at the powder material-fed side, a classification chamber defined by the center core, the separator core and a side inner wall of the casing, and a flow path encircling the louver ring, wherein in a horizontal cross section of part of the classifying apparatus where the part contains the powder material feeding port and the louver ring, the louver ring is located at a position where the louver ring does not intersect with an extended line of a wall surface of the powder material feeding port at the side of the louver ring.
