A rotor of an impact crusher is provided to increase material crushing efficiency by bumping materials against a blow bar, first and second blow plates, and a lining in order and then colliding the material with the blow plates again by installing the lining between the blow bars. An impact crusher has a rotor(200) installed in an inner crushing compartment of a body and combined by fitting blow bars(220,221) to plates(230,231) and blow plates installed in the body, and crushes materials by rotating the rotor. A crushing lining(250) is installed between the blow bars and settled to a lining fixing plate(260) welded between the plates by fixing bolts(251). The crushing linings positioned at the inner side further than both sides of the rotor are installed closely to the blow bar.
