When coal processing plants are far from the mine, overland coal conveyors can be used to connect the two. Disc brakes meet the requirements of these conveyors in normal stopping and parking operations, as well as providing vital emergency stop operation. When coal processing plants are an appreciable distance from the mine, how best to transport the coal from one to the other is a key consideration. It is not unusual for the processing plant to be tens of miles away, which might at first glance suggest delivery by truck. But overland conveyors can often provide a far more economical solution, providing cost reductions in the order of 20-40% or more. Of course with a conveyor that may run for miles, there are many design considerations to take into account; all of which will impact on long term reliability, availability and maintenance requirements. Transporting vast tonnages of coal overland, particularly where there are inclines involved, requires the highest levels of expertise in sophisticated conveyor and control systems.
