Discrete Element Method Services
DEM simulation for bulk material flow, handling and process optimisation
VKB Tech supports enterprise engineering teams with Discrete Element Method simulation for particles, powders, granules, rocks, crops and other bulk materials used in transport, mixing, crushing, milling and handling systems.
Realistic bulk material behaviour
Simulation-led insight into particle motion, contact forces and material flow
Bulk materials can behave unpredictably during transfer, loading, discharge, crushing, mixing and processing. DEM simulation helps engineers understand how individual particles interact with each other, with equipment surfaces and with the surrounding process environment.
VKB Tech provides DEM simulation services to help clients predict material flow, identify blockage and wear risks, estimate operational loads, optimise equipment geometry and improve machine performance before physical prototypes or plant modifications are committed.
Core DEM capabilities
Simulation services for particles, granular materials and bulk solids
VKB Tech delivers DEM studies for engineering teams that need to understand particle behaviour, equipment interaction and process performance under realistic operating conditions.
Bulk material flow simulation
Simulate flow through chutes, hoppers, conveyors, buckets, transfer points and process equipment to evaluate throughput, blockage, spillage and flow stability.
Particle interaction modelling
Model particle size, shape, density, friction, elasticity, adhesion and contact behaviour to represent realistic material response during operation.
Wear and impact assessment
Identify high-impact and high-wear regions, evaluate particle velocities and forces, and support liner, chute and equipment protection strategies.
Mixing, milling and crushing studies
Evaluate particle breakage, separation, blending, residence time, process efficiency and tool geometry for mixing and size-reduction processes.
Load prediction for structural design
Calculate realistic particle-induced forces and load distributions that can be transferred into FEA workflows for structural verification.
Multiphysics simulation support
Support coupled DEM-FEA, DEM-CFD and DEM-MBD workflows where particle flow interacts with structural, thermal, fluid or motion behaviour.
Applications
DEM applications across heavy industry, process equipment and machinery design
VKB Tech supports clients working with particulate and bulk materials where flow behaviour, particle interaction, equipment wear and realistic load prediction are critical to product or process performance.
Mining and metals
Simulation support for quarrying, excavation, conveyors, transfer chutes, buckets, crushing equipment and high-throughput material handling systems.
Mineral processing
DEM studies for crushing, milling, screening, mixing and separation processes involving rocks, ores, aggregates and mineral raw materials.
Material handling equipment
Flow optimisation for hoppers, bins, feeders, belts, transfer points and chute systems to reduce blockage, spillage, dust and equipment wear.
Agricultural machinery
Simulation of grain, seed, fertiliser, potatoes, crops and soil-engaging processes to improve machine performance and reduce crop damage.
Industrial process equipment
Assessment of mixers, rotating drums, mills, feeders, silos and handling systems where particle behaviour influences efficiency and reliability.
Coupled engineering analysis
DEM-based load extraction and multiphysics coupling for structural design, thermal processes, fluid interaction and moving mechanical systems.
Enterprise engineering value
Optimise bulk material systems before costly modifications or prototypes
DEM simulation gives engineering teams visibility into particle behaviour that is difficult to measure directly during operation. VKB Tech converts that insight into practical recommendations for design, performance, reliability and maintenance improvement.
How DEM supports engineering decisions
- Predict and improve machine and process performance
- Identify blockage, spillage, dust and high-wear regions
- Optimise transfer geometry, bucket shape, tools, mixers and blades
- Estimate real operating loads for structural design and FEA
- Reduce energy consumption, downtime, service cost and development risk
Typical use cases
Practical DEM studies for design, troubleshooting and optimisation
VKB Tech can support one-off investigations, design optimisation studies, root-cause analysis and integrated simulation workflows for new or existing equipment.
Transfer chute optimisation
Evaluate flow stream, impact zones, discharge angle, velocity, blockage risk, dust potential and wear patterns.
Bucket and tool geometry
Compare design variants for excavator buckets, blades, tools and contact surfaces to improve performance and reduce wear.
Mixing and process efficiency
Assess blending performance, segregation, residence time, material distribution and process uniformity.
DEM-to-FEA load transfer
Use particle force data to define realistic loads for structural analysis, durability checks and equipment verification.
Coupled simulation
DEM combined with FEA, CFD and MBD for deeper engineering insight
Particle behaviour often interacts with structural loads, airflow, heat transfer or moving mechanisms. VKB Tech supports coupled simulation workflows that help teams understand both the bulk material process and the equipment response.
DEM-FEA
Transfer particle forces into structural models to evaluate stresses, deformation, fatigue risk and equipment robustness.
DEM-CFD
Assess particle-fluid interaction for processes involving airflow, dust, drying, cooling, heating or filtration.
DEM-MBD
Evaluate interaction between granular material and moving mechanical systems such as linkages, drums, buckets and mechanisms.
