GERMANY-headquartered ContiTech is delivering 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’s conveyor belt systems have already been used in previous projects of Codelco.
The large-scale 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 will transport the mined rock, the mine operator implements energy-saving solutions. The steel cord belts from ContiTech are manufactured with an XLL Compound, a special, energy-optimised rubber composition. Since this rubber compound significantly improves visco-elastic properties, the indentation rolling resistance on the conveyor belt system is minimised. In comparison with conventional conveyor belts, this enables energy consumption during the transport of raw materials to be reduced by up to 25%, ergo reducing energy costs and CO2 emissions.
Alongside energy-optimised steel cord belts, the firm is also supplying innovative electronic conveyor belt monitoring and inspection systems, the ContiProtect, 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, says ContiTech.
A complementing product, the 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 ContiInspect 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 via the revolutionary Conti®Inspect 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. ContiInspect 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.
