Three years in development, BedRock Software, LLC’s newest program is said to represent a completely new generation of simulation software to manage and optimize an aggregates operation. AggFlow Design and Manage is a hybrid program that allows workers to work on-line or off-line and to share projects with other users at will. The sharing capability is intended to allow process engineers, consultants, and equipment dealers to work collaboratively when developing a plant optimization strategy. Simulation can be used to determine optimal production capacity for a particular equipment configuration; then users can input field sample data to compare what the operation is actually producing to its theoretical capability. This information can then be used to identify and eliminate bottlenecks and inefficiencies.

Atlas Copco offers a suite of seven underground loaders and trucks that use electricity as the primary power source. The Green Line, it says, is designed to help underground mines address challenges including energy efficiency, carbon emissions, and environmental footprints. Underground mine trucks include the EMT35 and the EMT50 (pictured), with respective loads of 35 and 50 tons. Said to be twice as fast as any diesel truck of similar size, the manufacturer touts the trucks as the “world’s most productive trucks.” By using electricity, energy consumption is reduced by up to 70 percent. Regenerative braking returns energy to the grid, meaning that about 30 percent of the energy consumed up a ramp is regenerated going back down.

Tracking operator fatigue
Caterpillar Global Mining entered an alliance agreement with Canberra, Australia-based Seeing Machines Limited to deliver and support operator fatigue monitoring technology. Developed by the Australian company, the monitoring systems use patented eye and head tracking technology to detect operator fatigue and distraction, as well as to alert the mine controller and the machine operator. The alliance agreement also supports collaboration in future product development. The Driver Safety System, a commercial system for mining trucks, is working on more than 20 mine sites and 1,500 vehicles.

Irock Crushers introduces the Wheeled Jaw Crusher-2644 for use as a primary crusher. Powered by a 350-horsepower Caterpillar C-9 Acert Tier 3 engine, the unit can produce up to 370 tons per hour. With a capacity of 10.5 cubic yards, the hopper was designed significantly larger than similarly sized crushers. The crusher is equipped with a 48-inch by 36-foot discharge belt that features a fixed discharge height of 11 feet — said to be the highest stockpiling height in the industry — and can easily be paired with screening units. A hydraulic adjusting chamber allows operators to adjust crushing size from a 2-inch minimum closed-side setting to a 6-inch maximum side setting. The machine includes a 24-inch grizzly bypass conveyor, as well as a 40-inch by 14-foot feeder with a 5-foot grizzly bar section to ensure proper classification of material.
