Sep 18, 2010 Belt conveyors for underground service usually are designed more rugged and operate at slower speeds than a comparable overland conveyor. 35, and 45 degrees. In Europe, they are 20, 30, and 40 degrees. A 20-degree troughing angle permits the use of the thickest belts, so the heaviest material and maximum lump size can be carried.
Conveyor systems. A conveyor belt is a system that carries material from one point to another. A conveyor system or material handling system consists of two key components; a loop of material known as the belt and two two pulleys fixed at either end. These pulleys work in a continuous circular motion to pick up material at one end of the belt ...
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.
