ROLLOUTS 12 AGGREGATES MANAGER / September 2016 Large-scale, semi-automatic excavator Komatsu America Corp. introduces the PC490LCi-11 hydraulic excavator, which is powered by a 359-horsepower, Tier 4 Final SAA6D125E-7 engine. It offers up to a 13-percent increase in productivity and 7 percent more arm crowd force and bucket digging force. With Intelligent Machine Control, it features a sensor package including stroke-sensing hydraulic cylinders, an IMU sensor, and GNSS antennas. The machine uses 3D design data loaded into its monitor to display machine position relative to the target grade. When the bucket reaches the tar- get surface, automation kicks in to limit over excavation. Other features include: auto grade assist, auto stop control, minimum distance control, facing angle compass, realistic 3D display, and a control box. Komatsu America Corp. | www.komatsuamerica.com Cone crusher line evolves Sandvik Construction says its CH540 represents the second step in a new gen- eration of cone crushers and is suitable for operators who want to increase pro- duction capacity, eliminate bottlenecks, reduce cost per ton, or improve product quality. The high-capacity crusher comes standard with Sandvik's new automa- tion and control system — SanRemo for Crushers. A dump valve ensures quick, safe tramp relief while wear parts have been adapted for longer life. Minimum welding is used on the crusher, which has also been designed to allow for faster change out of manganese. With feed sizes ranging from 1.7 to 7.3 inches, the crusher's capacity is rated at up to 295 tons per hour. Sandvik Construction | www.construction.sandvik.com Flexible crushing technology Sandvik Construction debuts SanRemo for Crushers, its new approach to crusher automation. The system builds on its ASRi automation system and continues to ensure the desired closed-side setting by compensating for moisture and hardness in the feed. It builds upon that, however, with ad- ditional monitoring, control, and data features, with access provided via a cloud solution. The automation is available in three service levels — bronze, silver, and gold — with the flexibility to use only the features currently need- ed, but upgrade whenever necessary.

This ultra-fines recovery unit can process up to 589 cubic yards of slurry per hour, recovering material as low as 40 microns to decrease the need for storage ponds or water treat- ment plants. The plant includes a centrifugal pump, a cluster of four hydro- cyclones, and a high-frequency dewatering screen on one chassis. The FM UltraFines also features a uniquely designed conical tank and anti-turbulence system, which the manufacturer says is essential in the process of ultra-fines recovery.
