Claims

[Claims for Utility Model Registration] 1. An impact crusher that discharges materials to be crushed into a rotor rotating at high speed from an outlet of the rotor using centrifugal force, and crushes the materials by colliding with a collision part provided around the rotor. In, the distance between the outer peripheral surface of the rotor and the collision part is
Impact type crusher set between 250mm and 350mm. 2. The impact crusher according to claim 1, wherein the rotation of the rotor is set at 50 to 70 m/sec. 3. The impact crusher according to claim 1 or 2, wherein the rotor outlet is opened near the outer peripheral surface of the rotor.
