Our Large Hydraulic Double Roller Crusher is equipped with an advanced Intelligent Hydraulic Protection System designed precisely for this scenario.

Double Roller Crusher

When an uncrushable foreign object drops into the rollers, the extreme spike in resistance forces the hydraulic system to automatically retreat the movable roller. This instantly widens the discharge gap, allowing the object to pass through safely without harming the durable high-chromium manganese alloy roller skins or overloading the motor. Once the item is discharged, the system automatically resets the rollers back to your precise preset gap within seconds—ensuring completely continuous, safe, and stable operation.
