Transport in Western Sahara is very limited by sea, road and air with camels being the primary means of transportation in the desert area. Road transport by buses remain the major mode of transportation. The longest conveyor belt in the world is 100 kilometres (62 mi) long, from the phosphate mines of Bu Craa to the coast south of Laayoune. The belt moves about 2,000 metric tons of rock containing phosphate every hour from the mines to El-Aaiun, where it is loaded and shipped.

A conveyor belt is the carrying medium of a belt conveyor system. A belt conveyor system is one of many types of conveyor systems. A belt conveyor system consists of two or more pulleys, with a closed loop of carrying medium—the conveyor belt—that rotates about them. One or both of the pulleys are powered, moving the belt and the material on the belt forward. The powered pulley is called the drive pulley while the unpowered pulley is called the idler pulley. There are two main industrial classes of belt conveyors; Those in general material handling such as those moving boxes along inside a factory and bulk material handling such as those used to transport large volumes of resources and agricultural materials, such as grain, salt, coal, ore, sand, overburden and more.
