In a method for comminuting mineral materials, the material to be crushed is crushed between counter-rotating crushing discs (32, 34) and transported onwards by means of a gas stream at a rate of 10,000 to 13,000 m3/h and/or a speed of at least 26 m/s. Also disclosed is a device for comminuting mineral materials, having at last one crusher (6) with counter-rotating crushing discs (32, 34) and at least one fan (7), which is suitable for blowing a gas stream into the crusher at a rate of at least 10,000 m3/h and/or a speed of at least 20 m/s, in order to convey the material to be crushed. |
