High-tech modeling contributes to more sustainable mining machines
Metso’s Process Technology Center in Colorado Springs, Colorado, USA, is developing virtual machines based on sophisticated multi-physics models. The use of this technology is rare within the mining industry, making Metso the leader in simulating these complex problems.
Multi-physics modeling refers to the simultaneous application of more than one physics-based model to a system. The modeling can include any combination of particle or fluid motion, heat transfer, magnetics etc. Millions of particles, plus all of the interaction between the particles and the machine, are often modeled. The data generated makes it possible to analyze in detail how particles move through the grinder or crusher and how forces are applied to the particles. Modeling opens up numerous opportunities to improve machine performance.
Analysis of complex problems
“Our aim is to provide a complete predictive capability for the performance of Metso’s equipment, as well as to provide a service to our customers for the ongoing optimization of their operations. Upon completion of the product development work, we will be able to predict capacities, energy consumption, product gradations and life of wear components for many of our applications,” says Jens Lichter, Operations Manager, Process Technology, Mining business line.
Utilizing the physics models allows Metso to improve on the design and function of minerals processing equipment and to innovate new machine designs for its customers. Modeling also allows Metso to provide its customers with design services for new plants or optimization services for existing operations.
Positive environmental benefits
This, in turn, benefits the environment, as any improvement in the efficiency of a mine or plant improves sustainability. Reduced energy consumption, improved mineral recovery, and better durability of wear parts all result in reductions in overall energy use, greenhouse-gas emissions, water consumption, and waste.
