Conveyor belts represent a high risk, because they have the ability to spread a fire over long distances. Fires on belt conveyors are mostly ignited by mechanical failures like frozen idlers, which is even more dangerous in combination with coal dust. The fire safety requirements are similar for the most hard coal mining countries.
Because coal mining operations use conveyor belts extensively to move materials, you must be able to count on your mining equipment to work efficiently without unscheduled downtime. Every time you have to stop production for unexpected problems like repairs or housekeeping, profitability drops.
The tear drop conveyor offers significantly greater maneuverability, and can handle much tighter curves and turns than conventional conveyors. Another type of conveyor system, often used in coal mining, is a vacuum conveyor. This system involves the use of air injector pumps to generate the vacuum, a separation hopper to remove the coal from ...
