FLSmidth Excel LLC says it new Sentinel Advanced Hydraulic System is an affordable, aftermarket solution for aggregate producers who want to automate their cone crusher’s clearing capabilities without the purchase of a new crusher. The system provides constant clamping force between the adjustment ring and the mainframe, reducing “ring-bounce” and the related maintenance and repair costs. A remote power unit provides cavity clearing with the turn of a switch and the push of a button. The company says the system’s tramp release cylinders require little or no modification to the existing cone frame during installation, and feature protective boots to minimize potential damage and dust contamination.
