- Description
- Long overland conveyor systems have become an increasingly popular method of transporting bulk materials over relatively large distances from mine sites to fixed transport infrastructure - such as railways or ports. Lateral belt drift occurs in long overland systems wherever a horizontal curve exists in the system. This is due to a motivating force that stems from the tension present in the conveyor belt. This belt drift can be hazardous and operationally undesirable and as such, a number of control mechanisms have been developed to assist in the control of belt drift to an extent where it is tolerable. In this paper, a new method of control for belt drift is described in an effort to add- to the existing control methods- a complementary technique which will allow better control and ultimately a more reliable and viable conveyor system. The current profile of a horizontal curve section of a conveyor system is a constant radius curve- a segment of a circle- that simply sweeps through the desired angle. A belt tension increase over the length of the curve results in a corresponding increase in the extent of the belt drift. If a non-constant radius curve is adapted and used in such a way that the increase in curve radius over the length of the curve serves to counteract the increase in belt tension, a single, constant value for belt drift can be attained. This is an improvement and alongside current techniques can serve to increase the control over belt drift that a designer and mine site can expect to achieve.
