The Sentinel Advanced Hydraulic System from FLSmidth Pekin LLC offers an aftermarket solution for aggregate producers and mining operators who are looking to automate their cone crusher’s clearing capabilities, while avoiding the required capital outlay of a new crusher purchase.

Manual crusher cavity clearing is a dangerous and time-consuming process, which creates additional costs due to hours of required downtime. An automated cavity clearing system provides safe, virtually instant lift of the cone crusher’s bowl in the event of a tramp iron incident, allowing the uncrushable material to drop out of the bottom of the crusher. In the event of uncrushable material not immediately passing, the cavity can be cleared and the producer can be back in operation in fewer than 15 minutes, according to FLSmidth.

The Sentinel advanced hydraulic system uses a remote power unit that provides cavity clearing with the simple turn of a switch and push of a button. Installation of the system’s tramp release cylinders requires little modification to the existing cone frame. As an additional benefit, the system provides constant clamping force between the adjustment ring and the mainframe, reducing “ring-bounce” and cutting down on related maintenance and repair costs. And the tramp release cylinders feature protective boots to minimize potential damage and dust contamination to the cylinders as they work to hold the adjustment ring down.

The Sentinel advanced hydraulic system also offers a bowl adjustment option that allows the producer to quickly adjust the cone crusher’s closed-side setting (CSS) and simplifies the process of turning the bowl for liner changes.

The Sentinel Advanced Hydraulic System is currently available for retrofitting crusher models from 4.25 through 7 ft. (1.3 through 2 m) in diameter.
