High-speed rotor impact design achieves crushing efficiency by returning materials through multiple impact chambers sequentially.
When the machine is operated, the rotor rotates at high speed driven by the motor. When materials enter the blow bar action area, it is crushed by impact with the blow bar on the rotor, and being thrown to the impact device to crush again. Then it bounces off the impact lining, returning to the blow bar action area for re-crushing. Materials from large to small enter the first, second and third impact chambers for repeated crushing until the materials are crushed to the required particle size and discharged from the outlet port.

Impact crushers are ideal for processing medium-hard and soft materials such as limestone, coal, calcium carbide, quartz, dolomite, and concrete recycling aggregates.
The output particle size can be adjusted by changing the gap between the impact plate liners and the rotor blow bars, or by altering the rotor rotation speed.
The main wear components include the blow bars mounted on the rotor, the impact plates (or lining boards), and the side liners inside the crushing chamber.
Multiple impact chambers (typically 2 or 3) allow for progressive size reduction, resulting in a more cubic shape of the final product and less internal stress in the crushed aggregates.
While it can handle materials with minimal moisture, highly sticky or wet raw feed may adhere to the impact chamber components and potentially lead to clogging in the outlet port.
