The viability of the high angle conveyor system application lies in the degree of economic advantage it offers over the conventional truck system it is to replace. For economic comparison both the high angle conveyor system and the truck haul system are developed for the same mining sequence, pit configuration and production schedule.

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 ...
