Energy-optimized conveyor belts reduce energy consumption by up to 25% whilst electronic conveyor belt monitoring and inspection systems ensure safe and reliable operation with minimal maintenance costs for Chilean copper mine.

A large-scale project is now under way using innovative conveyor belts and belt monitoring systems for the development and expansion of the Chilean copper mine in El Teniente, which is run by mine operator Codelco. More than 20 kilometers of steel cord belts are to be installed between 2013 and 2017. ContiTech conveyor belt systems have already been used in previous projects of Codelco. The conveyor belt specialist received this latest order via Tenova TAKRAF from Leipzig.

Protect the environment
The project Nuevo Nivel Mina is intended to open up new copper reserves in deeper layer of the mountain so that increased underground mining can now take place. With the new conveyor belt system, which transports the mined rock, the mine operator has implemented energy-saving solutions. The steel cord belts from ContiTech are manufactured with an XLL Compound, a special, energy-optimized rubber composition. Since this rubber compound significantly improves visco-elastic properties, the indentation rolling resistance on the conveyor belt system is minimized. In comparison with conventional conveyor belts, this enables energy consumption during the transport of raw materials to be cut by up to 25%. In this way, energy costs and CO2 emissions can be significantly reduced.

Improved safety and reliability
Alongside energy-optimized steel cord belts, the ContiTech Conveyor Belt Group is supplying innovative electronic conveyor belt monitoring and inspection systems for El Teniente. These systems are well suited for the diverse challenges of the copper mine and guarantee a high degree of safety and reliability.

ContiProtect monitoring systems protect conveyor belt systems against serious damage, thereby making a major contribution to enhanced operational reliability by reducing the number and length of malfunction-related downtimes. ContiProtect Splice Elongation Measurement is designed to monitor larger conveyor belt systems and uses magnetic markers to detect irregularities in splice length.

"On conveyor systems with ever more stringent safety factors and ever increasing conveyor belt strengths, monitoring the splice increases operational reliability," says Arndt Bunzel, application engineer in the Mining World segment at the ContiTech Conveyor Belt Group.

Belt Rip Detection uses conductor loops vulcanized into the conveyor belt to detect longitudinal slits as early as possible. With improved conductor loops and low susceptibility to electromagnetic interference, the belt monitoring system prevents error messages and, in turn, costly conveyor downtime. Online support is also available. On request, the experts from ContiTech can log into the system and remotely check and optimize processes.

ContiInspect systems provide data that can be used to derive reliable forecasts about the remaining service life of the conveyor belt, allowing operators to estimate investment costs more accurately. This makes a vital contribution toward reducing operating costs and protecting the environment. With the aid of laser sensors, the mobile Belt Thickness Measurement system determines the thickness of the conveyor belt across the full width of the belt. Surface damage can be detected at an early stage thanks to the Continuous Surface Inspection system.

State-of-the-art scanning technology is used to examine the surface of the conveyor belt and generate a detailed image of the belt surface and its condition. The ContiInspect belt monitoring systems can be used while the belt system is in operation. This avoids conveyor downtime for time-consuming inspections and reduces the expenses involved in conveyor belt inspections. The Cord Monitoring uses magneto-inductive technology to monitor the steel cords of the tensile member and thereby improve the safety and reliability of the conveyor belt.

In the development of its electronic monitoring systems, ContiTech uses synergy effects across the corporation and builds on the know-how of the Continental Automotive Group, which among other things develops and produces pioneering electronic systems for the automotive and commercial vehicle industry. From this collaboration derive innovative solutions for more security in conveyor belt systems. The newly developed belt monitoring systems of the ContiTech Conveyor Belt Group meet the high standards of the automotive industry and guarantee a high level of reliability.
