Conveyor belts are one of the main sources of energy consumption inside mining sites. Studies show that indentation rolling resistance is the primary source (61%) of energy losses in conveyor belt applications. Belt manufacturers are investing to develop rubber compounds with properties that help lower belt indentation resistance. When Kevlar®
In order to adjust belt conveyors in alignment with progress in the mining longwall, conveyor belts either have to be short-ened or lengthened. To enable this, a Voith TurboBelt Storage Loop can be integrated into the belt conveyor system. Voith Storage Loops can hold approximately 250 m of belt, thus minimizing belt connections.
Conveyor, any of various devices that provide mechanized movement of material, as in a factory; they are used principally in industrial applications but also on large farms, in warehousing and freight-handling, and in movement of raw materials. Conveyors may be only a few inches in length, or they

Bulk conveyors are the lifeblood of your stockpile and process throughput in the mine. Downtime prevents you from meeting your mine plan and production goals. Overland conveying or "truckless" mining systems are especially critical as they represent a single point of failure. Mines simply don''t have spare conveyors.
A conveyor belt is the most important and, at the same time, the weakest link of the belt conveyor system. Conveyor belt damage is a frequent cause of unplanned downtime, particularly when the belt conveyor system serves as the main mining transportation. Partial or full damage of conveyor belt occurs as a result of several factors.
