Studies into DEM Simulation Technology for Conveyors
4.20 Development and application of DEM simulation technology for design and troubleshooting of conveyor transfers
Modelling and troubleshooting complex conveyor transfer can be a formidable task. This paper presents the application of DEM technology to model and examine:
- different types of transfer (e.g. rock box, hood-spoon, micro-ledge chute)
- wear regions
- dust issues
- diverters/flop gates
- fines/dribble chutes
Industrial case studies will be presented to demonstrate solutions and application of the new technology.
Andrew Grima, Principal Design Engineer, Bulk Materials Engineering Australia, University of Wollongong
4.50 Application of DEM in the Transportation of Bulk Solid Materials on Belt Conveyors
Modelling and experimental results regarding the transportation of a number of bulk solid materials on a troughed belt conveyor are presented to determine the loads exerted on the belt. Bulk solid material behaviour during the transition from the troughed belt to discharge is also presented.

11.30 Conveyor System Health Monitoring
The bulk material industries, such as coal or iron ore, rely on conveyor systems for transportation. A critical belt failure could result in thousands of dollars per hour in lost production, with some serious events running into millions of dollars. Thus it is important for operations to understand the health of their conveyor systems to effectively schedule maintenance and mitigate the risks of catastrophic failures. There are a number of new and emerging technologies that can and are being applied to conveyor system health.
This presentation will examine the issues with conveyor systems and some of the techniques that can be applied. In particular the on line monitoring of a belts surface as an aid to maintenance and a case study of how this is being applied for a coal mining operation.

Shaun Saggers, Mechanical Engineer, AUSENCO
1.10 Case study: Optimising the throughput of rail dump stations, via modelling and control system changes
- There is an obvious economic advantage in decreasing the average train unloading time in a dump station as it results in increased throughput for the facility.
- Another issue that has been experienced in operating dump stations has been coal building up above the level of the track causing the wagons to ‘plough’ through the coal resulting in the real concern of train derailment.
- This paper presents case studies where computer based dynamic modelling of coal rail dump stations was used to assess and optimise the throughput and minimise the potential for ploughing.
- The modelling included the flow of coal discharging from the rail wagons and flowing through the dump station.
- The modelling also incorporated factors that can affect the dump station performance including positioning and sequencing of the wagon door release triggers, hopper design, control of the conveyor speeds, train speed etc.
- The effects of “sticky coal” resulting in hang up of coal in the wagons and the control of the robotic wagon vibrators used to address this issue were included in one case study

1.50 BMH Simulation - A Cornerstone of Fit-for-Purpose Design
Supply chain constraints, behaviour of materials handling system interfaces and the way the supply chain is operated and managed have a significant influence on BMH design requirements. We look at a number of alternative supply chain paradigms and the differences between fit-for-purpose BHM system designs to suit the needs of the supply chain.
