Large Rock Crushing Ability: Can crush rocks ranging from 600 to 900 mm.
Low Maintenance Cost: Equipped with wear-resistant rotors and hammers for durability.
Versatile Applications: Used in construction, road building, and concrete production.

Working Principle:

Large rocks are fed into the hopper.
The rotor system spins at high speed, hitting the material with hammers to break it.
 The crushed material is screened to achieve the desired size.
 The final product is ready for use in concrete production, asphalt, and filling materials.
