PROBLEM TO BE SOLVED: To provide a cracking apparatus 100 with structure capable of maximally producing products of desired size with minimum generation of useless powder. SOLUTION: Rotation of a first cracking body 110 and a second cracking body 120 in the downward moving direction at a position where outer peripheral parts of cracking disk parts 210 are mutually superposed, winds raw material charged to the superposed part from above into a gap between one cracking disk part 210 and the other spacer disk part 220 to crash into particles. The raw material is crashed into particles with no impact, thus generation of useless powder can be minimized and products of desired sizes can be maximally produced. COPYRIGHT: (C)2008,JPO&INPIT
