PROBLEM TO BE SOLVED: To provide a bone mill of a novel mechanism capable of rapidly pulverizing bones to a sired sizing. SOLUTION: Respective cutter units 12 and 13 are provided with plural sheets of disks 15 arrayed at prescribed intervals in parallel. Knife blades 40 for pulverizing the bones are formed on the peripheral surfaces of the respective disks 15. The disks 15 of the first cutter unit 12 and the disks 15 of the second cutter unit 13 are so positioned as to be alternately fitted in spacings. The disks 15 of the respective cutter units 12 and 13 are rotated inwardly with each other. When, therefore, the bones to be pulverized are supplied to both cutter units 12 and 13, the bones are taken by the disks 15 rotated inwardly with each other into the spacings between the disks and the knife blades 40 of the disks 15 bite into the bones, thereby crushing the bones. As the bones pass between the disks 15 of the first cutter unit 12 and the second cutter unit 13, the bones are pulverized by the disks 15 positioned to fit each other.
