Improved crusher reliability and availability

The electric dump valve control system checks the Hydroset hydraulic pressure 200 times per second. When pressure rises beyond a preset limit, the system instantly drops the main shaft to reduce mechanical stress on your crusher, greatly improving its performance and reliability.

  • Improved safety - Fewer breakdowns minimize risk of injury to maintenance personnel thanks to fewer maintenance hours.
  • Improved service life - Significant increase in service life of structural components and bearings due to reduced exposure to pressure peaks.
  • Avoid costly equipment damage - An output signal from the control system notifies operators that the crushing chamber is opening, enabling corrective action to remove the unwanted object from the processing circuit.

*Compatible with the following Sandvik cone crusher models:
Retrofit kit: CH660, CH860, CH865, CH870, CH890, CH895, H6800, H7800, H8000, H8000i, H8800, CH880
