A crushing and mill device includes an outer rotary disk (1) and an inner rotary disk (2) put in said outer rotary disk, wherein, the outer and inner rotary disks communicate the inlet (3) of the feed material, some through holes (20) communicating the outer and inner disk are provided on the sidewall of the inner disk, some carrier plates (4) for carrying the feed material are provided on the places that correspond to the through holes (20) on the disks. The rotations of the outer and inner disks are driven by motors, and the rotations direction of the inner and outer disks are opposite. The sidewall of outer disk has an outlet (10) of the feed material. The feed material enters the inner and outer disks from the inlet, and the feed material is shot off oppositely by the rotations of the outer and inner disk. The feed material passes the through holes of the inner disk and impacts with each other to be broken and milled. The particulates formed by milling are shot off from the outlet on the sidewall of the outer disk. The device can lower energy consumption and raise output.
