Cost-efficient and Application-oriented Design of Steel Cord Conveyor Belts for the Mining Industry
Conveyor belts in the mining industry are facing ever higher demands as regards conveying capacity, conveyor length, service life and energy efficiency. In addition to designs according to various general standards manufacturers further develop their products for better economy.

With the use of XLL rubber compound, not just the required drive power but the installed motor power can also be reduced. Due to the reduced motion resistance, a conveyor belt with a smaller nominal breaking strength than the conventional conveyor belt can be selected. As a result, the conveyor belt and the drive and tail pulleys of the belt conveyor system become “lighter” and more economical.
The end result is a belt conveyor system with a “lighter” and more economical conveyor belt, “smaller” motors or with a reduced number of motors, smaller drive and tail pulley diameters, a lighter tensioning device, and lighter steel construction, etc., which makes it possible to sharply reduce the costs for the entire system. Table 2 shows a feasibility study for a parallel OLC-2 long-distance conveyor at KPC mine (Kaltim Prima Coal), where the belt conveyor system is compared to a steel cord conveyor belt with and without a bottom XLL rubber compound. In , the OLC-1 long-distance conveyor was described as well (Fig. 5).
