Claims

[Scope of Claim for Utility Model Registration] (1) A rotary disk provided with an impact piece on one side and a classification member on the other side, a casing that covers the rotary disk, and a casing that penetrates the casing and is provided with an impact piece of the rotary disk on the other side. A raw material supply channel communicating with the side where the piece is provided, a fine powder discharge port provided in the casing located on the classification member side in the axial direction of the rotary disk, and a fine powder discharge port provided in the casing located on the periphery of the classification member. The fine powder discharge port is connected to the suction blower via the fine powder collector, and the coarse powder discharge port is connected to the raw material supply path, so that grinding, classification, and re-grinding are carried out continuously. This is an impact crusher with a built-in classification mechanism, wherein the classification member is a substantially conical member attached with its axis aligned with the rotation center of the rotary disk, and the impact pieces are attached to the rotation center of the rotary disk. A built-in classification mechanism characterized by comprising a plurality of substantially rectangular parallelepiped members radially attached around the center of rotation, and forming a retention space for materials to be crushed between the impact piece and the casing. impact crusher. (2) The classification member described in claim (1) of the utility model registration claim is characterized in that the classification member is constituted by a substantially conical member whose bottom surface and the generatrix line form an angle in the range of 15° to 30°. Impact crusher with built-in classification mechanism. (3) The width of the impact piece in the direction of the rotational axis is 0.25 to 0.
．． An impact crusher with a built-in classification mechanism as set forth in claim (1) of the utility model registration, characterized in that a retention space for the material to be crushed is formed by forming an impact crusher with a built-in classification mechanism. (4) Utility model registration claim No. (1) characterized in that the casing located at the periphery of the rotary disk is provided with a separate ring that maintains a small gap from the outer peripheral surface of the rotary disk. An impact crusher with a built-in classification mechanism as described in section.
