And while the design of these machines is highly site and material specific, there are two requirements that the mining industry always demands of their belt conveyors: safety and reliability. Safety Safety practices have come a long way since the canary-in-the-coal-mine days. Today, safety is heavily regulated in every aspect imaginable.Depending on the material on the conveyor belt, fire can accelerate very rapidly, resulting in extensive damage. Bearing failures can be very expensive both in terms of direct damage costs but also the downtime required to repair and replace. For example, an 8km conveyor belt for copper/molybendum mine can extract $320,000 per hour .
