Terex Finlay has introduced a new C-1540 direct drive cone crusher to the range of its tracked mobile cone crushers. This aggressive machine incorporates the proven 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 maximising throughput and minimising crusher wear.

The standard 5 m? (6.5 yd?) hopper/feeder on the plant has been designed with a low feed-in height so that the machine can be fed directly either by primary crusher, excavator or shovel. A key feature of the hopper is the standard automated metal detection and a purge system that has been designed to protect the cone chamber and reduce downtime by removing metal contaminants via the purge chute.
