How Impact Crushers Work: A Comprehensive Guide
Crushing Equipment / March 11, 2023 / 5 minutes of reading. An impact crusher is a machine used to crush materials by impact energy. It works by feeding the material into a rotating rotor, which is equipped with a series of hammers. As the rotor spins, the hammers strike the material, causing it to break into smaller pieces.
