PROBLEM TO BE SOLVED: To provide a grinding classifier which can reduce static pressure load in a classification process by reducing a content of included coarse powder fresh from a finely dividing process under a constitution using a common blower adaptable to a classifier and a grinder, with other advantages such as being able to prevent coarse particles from being included, maintain stable production conditions for a long time and also, achieve an efficient installation space use or power consumption. SOLUTION: This grinding classifier (50 and 60) is of a cyclone type and sucks and conveys a raw material and a ground particle using the common blower 80. In addition, the classifier (50 and 60) is constituted of a secondary air inflow hole 53, a guide cone 54 for making an ascent of a ground microparticle, and an exhaust pipe 55 for the ground microparticle. After capturing the ground particle, the first cyclone classifier 50 and the second cyclone classifier 60 sucks and discharges the micropowder upward. COPYRIGHT: (C)2011,JPO&INPIT
