PROBLEM TO BE SOLVED: To provide an apparatus which produces with ease fine crushed particles having a particle size of several micrometers, enable a continuance of the production conditions over a long period of time (prolonged time), and grasp the crushed condition numerically in real time quantitatively. SOLUTION: An air current type crushing and classifying apparatus includes at least a jet nozzle jetting a jet blast toward a crushing chamber inside, an acceleration tube with one end connecting with an end of the jet nozzle and the other end opening to the crushing chamber, a crushing nozzle opening to the acceleration tube and having a supply tube supplying objects to be crushed to the jet blast, and a colliding member installed opposed to the jet nozzle and having a crushing surface pulverizing the objects to be crushed by a direct colliding together with the jet blast. The apparatus is provided with a manometer above a confluence position of the acceleration tube and the supply tube to manage a supply state of the object to be crushed to the acceleration tube with the measured value by the manometer.
