Nov 16, 2021 Impact crushers include single-rotor impact crushers and dual-rotor impact crushers. Among them, the single-rotor impact crusher has a relatively simple structure. The material pieces are fed from the feed port. In order to prevent the material pieces from flying out during crushing, a chain curtain is installed in the feeding direction of the feed port. European Type Impact Crusher is equiped with heavy rotors. Since the rotor is the heart of the crusher, and is the strictest part in the impact crusher during checking and accepting process as well as is very crucial during working process, we developed and produced the heavy rotors with the firm structure to obtain higher inertia moment.
