PROBLEM TO BE SOLVED: To provide a crushing apparatus the crushing efficiency of which is made excellent by lessening a bad influence of a supply part of an object to be crushed. SOLUTION: This crushing apparatus is constituted so that compressed gas to be supplied to an inlet 5 is throttled in a throat part 6 arranged on the downstream side of the inlet 5 and expanded in a gas speed accelerating part 7 arranged on the downstream side of the part 6 to form a jet stream, the object to be crushed is supplied into the formed jet stream from a supply part 8 of the object to be crushed which is arranged on the downstream side of the part 7, the object to be crushed is jetted from a tip outlet of a speed accelerating nozzle 2 for accelerating the speed of the object to be crushed in a speed accelerating part 10 arranged on the downstream side of the part 8 and the jetted object to be crushed is made to collide against a collision member 4 arranged oppositely to the nozzle 2 and crushed. The cross-sectional shape of the part 10 is made long vertically. A current of the object to be crushed in the part 8 is regulated so that the object to be crushed is supplied perpendicularly in the axial direction of the part 6. COPYRIGHT: (C)2004,JPO&NCIPI
