It’s essential that every stage within a mining operation pulls its own weight. This rule applies to screening media and mineral segregation decks, to dewatering equipment and ventilation systems. The productivity cycle begins at the mine face and the scraping of vast geological commodities, but this valuable asset would represent nothing more than a mountain of potential profit without the support of these subsystems. Conveyor equipment governs this arrangement by providing the ambulatory force that transports the mineral resource from a currently active vein or seam, dispatching the aggregate material through shafts and out to the open face of the mine.
Take a few steps backwards to see the full picture. The conveyor system extends for kilometres below sub-surface excavations. A horizontal belt is mounted on a series of heavy-duty rollers and set in motion by massive electrical motors. The belt can be narrow or wide, mounted flat or oriented to cope with an incline, but all of these constructs share one common factor: They’re built tough. The aggregate matter being conveyed away from the seam is sharp-edged and coarse, thus the conveyor belt has to be made from a robust material. This one characteristic presents certain challenges, chief among them would be the balancing of physical flexibility against abrasive force. Polyurethane composites are popular in this scenario as the material can easily withstand the cuts and scrapes causes by the coarse flow of aggregate material.
The belt is sized to match the productivity cycle of the mine. Additionally, it’s typically reinforced to account for the transferred load. Polyurethane is a popular base material due to the polymer’s abrasion resistance characteristics, though tougher solutions with alloy-reinforced segments are available for heavy industry applications. Equipped with high tensile strength properties, the steel cords add an underlying layer of support when load conveyance conditions are at their most grueling.
Rollers and pulleys interlock with the rotating shafts of electrical motors to provide a smooth driving force. Additional components within this arrangement include roller cleaning blades, belt cleaners and toughened plastic bumpers. The bumpers simply guide the aggregate stream through the kilometres of tunnel, keeping the torrent firmly within the bounds of the conveyor system.
Used in the roughest and harshest environments that our planet can throw at us, conveyor equipment provides an arterial flow of valuable mineral-laden ore, mineral and quarried rock. The flow challenges every moving part of the system, threatening to choke rollers and abrade belt mechanisms, which is why every component has to be made from tough materials with ample reinforcement. Strong as each component must be, the robustness factor is always balanced by an intrinsic flexibility multiplier, an inbuilt capacity for flexing across rollers and climbing tough inclines.
