The C-1540 portable crusher incorporates the Terex 1000 cone crusher that can accept an all in feed and features direct variable speed clutch drive and “on the fly” hydraulic closed side setting (CSS) adjustment. A key feature of the chamber is an overload protection system with automatic reset that permits uncrushable material to pass through and be discharged efficiently from the machine. The feed-in box to the chamber is fitted with an ultrasonic level sensor that is calibrated to the feeder to ensure that the chamber is consistently choke-fed for maximizing throughput and minimizing crusher wear. 

The standard 6.5 cubic-yard hopper/feeder has a low feed-in height so that the machine can be fed directly either by primary crusher, excavator, or shovel.
