To provide a crusher with which a crushed particle having a required particle size can be obtained in high efficiency by improving colliding and crushing efficiency in a crushing chamber and to shorten production grade changing time.
This crusher is provided at least with the crushing chamber in which a supplied material is crushed by compressed air jetted from a plurality of nozzles and a rotating rotor above the crushing chamber and the crushed material made to flow in the rotor from the crushing chamber is sorted into fine powder and coarse powder by centrifugation. In this crusher, the nozzles are arranged so that the compressed air jetted from one of the nozzles is made to collide primarily against that jetted from other nozzles together with the material to be crushed and further a speed width adjusting means for narrowing speed width of the compressed air jetted from a plurality of nozzles is provided.
