(about one year) on the fi rst large-scale prototype system, commercialisation began in 1983 at a USA major conveyor manufacturer, Continental Conveyor. T e fi rst commercial installation was a 60° incline system, at a western USA coal mine, elevating 2,000 t/h of coal to a train-load out system. It did not take a long period of scrutiny and acceptance before this high angle conveyor found use in the most rugged requirements of an IPCC system. T is was only the second commercial sale, and after more than 150 commercial installations, it remains arguably the most signifi cant high angle conveying system.


Sandwich belt system proves success in Serbian mine In 1984 a copper mine in Serbia, already using pit perimeter crushing and conveying, decided to move its primary crusher deep into the pit and to use a sandwich belt high- angle conveying system to elevate the ore continuously, directly out of the pit, along the


high wall to the pit perimeter where it then transferred to a conventional conveyor for the remaining haul to the plant. T e system had impressive features including 2,000mm wide belts that elevated 250mm coarse ore, at 4,000 t/h, over six 15m high benches for a total 90m of net lift. T e system proved its worth in several notable ways:





It reduced the truck fl eet by 10 trucks, causing zero emissions to the air and greatly reducing traffi c congestion in the pit





It precluded the need for 4km of haulage ramps, 3.5km of which would be of constant ascent.


• Overall, it saved US$12 million per year


Meeting the challenges of today’s mining industry T e sandwich belt high-angle conveyor off ers the link to optimisation of any IPCC system,
