Abstract

The unloading processes of rail-based logistic systems for dry bulk are currently complex or have relatively low throughput. It should therefore be possible to increase the logistic performance by redesigning this process. The Kiruna Wagon Helix Dumper Solution (HD) unloading process offers low complexity and extreme capacity. Its logistic performance has been compared with the traditional Rotary Car Dumper Solution (RCD). The comparison was performed by analysing a case study and comparing key performance indicators. The results show that the HD system significantly outperforms the RCD system in every aspect, with substantially higher reliability, availability, and safety. In addition, the HD solution emits substantially less noise and dust at a stunning 57% less CO2 per transported tonne. For annual volumes from 10 million tonnes, the logistic cost of the HD system per unit volume is 15 to 35% lower and, in contrast to the RCD system, almost unaffected by the annual volume. While this is an advantage for larger mines, it makes smaller mineral deposits worthwhile to develop. In addition, the high unloading rate enables the direct loading of ships, allowing significant additional savings. Kiruna Wagon products meet industries' high demands for maximised payload, safety, and environmental protection. Kiruna Wagon solutions are designed using extensive experience working with mining logistics in an often-challenging global market. Kiruna Wagon has continued delivering world-class ore logistics to leading global mining operations for over two decades. This Helix Dumper transport solution is an existing technology currently in service internationally and has been operating in Sweden since 2012 out of Pitkäjärvi, travelling in all weather conditions. RCR Mining Technologies holds the Australian Kiruna Wagon technology license.
