Across the global mining sector, Discrete Element Method (DEM) simulation has become a standard feature of transfer chute design. But according to Weba Chute Systems, the danger lies in confusing a verification tool with a complete design methodology.
“Across the industry, the use of DEM has become mainstream,” says Mark Baller, Managing Director of Weba Chute Systems. “Where we differ is in how the chute is engineered. While DEM software is often used to model material flow, it is fundamentally a simulation and verification tool rather than a design tool. DEM can validate and optimise a chute design by analysing how material behaves within it but the engineering design itself must first be developed using sound design principles and application expertise.”
For Weba Chute Systems, effective chute design starts not with software but with engineering expertise and practical knowledge gained from designing more than 5,000 transfer points worldwide. This experience, combined with proven engineering calculations, forms the foundation of every chute design.
“We use the knowledge and practical experience we have accumulated over decades, together with sound engineering principles, to develop the chute design,” he explains. “Only once that design is complete do we use DEM software to verify and validate its performance, ensuring it will operate as intended under the specified conditions.”
