Services List

At TUNRA Bulk Solids, we complete between 200 and 250 major consultancy projects each year which cover the entire spectrum of bulk solids handling and storage applications. We are leaders in providing conceptual solutions to any bulk materials related task or problem that may occur in your plant.Our comprehensive laboratory test facilities and our highly qualified and committed team of engineers and consultants assist you to overcome existing handling problems and to plan new projects to ensure future trouble-free plant operation.Detailed information about the services offered by TBS can be viewed below either by Industry, Material Type or Handling Problem.For further information about a specific service or if you want to make an enquiry, please contact us directly or use our contact form.
  • Services By Handling Problems

    DEM and Calibration Services

    Discrete Element Modelling (DEM) has proven to be an extremely effective and valuable tool for analysing and optimising particulate flow in a wide range of bulk material processing and handling operations.

    TUNRA Bulk Solids (TBS) provides various services applying DEM ranging from troubleshooting, design audits and concept design to fundemental research and contact model development.

    The TBS DEM methodology incorporates a first-principle continuum approach to ensure correct simulation outputs.

    Typical outputs of DEM analyses include, but are not limit to:

    • General flow observations
    • Expected material trajectories
    • Quantitative prediction of velocity profiles
    • Qualitative prediction of chute liner wear
    • Centralised loading of receiving conveyor belts
    • Qualitative estimation and evaluation of belt wear
    • Hopper/feeder interface design
    • Adhesion/build-up of bulk materials on equipment surfaces
    • Particle degradation

    Additional competencies are available for coupling of DEM with Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA) to investigate specific problems such as passive dust control in transfer chutes or the interaction between bulk materials and materials handling equipment.

    Examples of typical projects involving DEM include:

    • Transfer chutes (from simple one-to-one transfers to complex, multi-bifurcated systems)
    • Hoppers and Feeders
    • Train loading and unloading operations

    The following case studies highlight a selection of projects completed by TBS using DEM analysis:


    Calibration of Bulk Material Parameters for DEM

    To obtain realistic simulation results and accurate characterisation of the material properties used in DEM is essential.

    TBS offers calibration services for DEM simulation parameters. In addition to standard flow property tests, a set of physical bench-top tests can be conducted on bulk material samples provided by customers, including the determination of:

    • Angle of repose
    • Inclining wall friction – single particles/consolidated bed
    • Particle shape characterisation
    • Rock-box flow testing
    • Chute liner adhesion testing
    • Particle Degradation
