ABB will automate the 13-kilometer conveyor system at the Chilean copper mine

ABB, the leading power and automation technology group, has won an order from Chile's TenovaTAKRAF to automate the world's most powerful conveyor system at the Chuquicamata copper mine in Chile. The conveyor system delivers underground copper mines directly to a centralized plant 13 kilometers away from the mine.

After the completion of the project, the conveyor system will become one of the largest and most complex projects in the world. The slope is large and the distance is long. The conveyor belt transports 20MW and 55MW, which is equivalent to the electricity consumption of 41,000 households. In the final phase, the system will deliver 11,000 tons of material per hour, equivalent to the freight volume of 158 freight trains.

The order consists of a complete power and automation solution, including gearless drives, motors, instrumentation and power supply. These devices will be custom designed to meet the site requirements to optimize power, control, measurement and actuation of the conveyor system. The solution will fully integrate the power and automation of the conveyor belt through ABB's flagship control system 800xA and the Mining Transfer Control Program (MCCP) to ensure optimal power quality and control throughout the system.

A key feature of this solution offered by ABB is its gearless conveyor drive system. This advanced solution meets very high load requirements and the necessary power availability; this is not possible with conventional drive solutions.

The gearless conveyor drive eliminates the need for a gearbox on the motor, which greatly reduces the number of major wear parts, reduces maintenance and ensures a longer service life. In addition, there is an advantage in reducing the footprint of the drive system and the number of instruments required. Fewer parts increase the reliability and efficiency of the entire conveyor system.
