Physical & Analytical Modeling with Bulk Materials

Are you developing a unique process or design for a challenging bulk solid?  Jenike & Johanson has the experienced staff, knowledge, and specialized tools to perform both physical and real-world analytical modeling studies.  We understand the importance of making sure the models are accurately scaled geometrically and with respect to bulk material flow properties.

Physical Modeling Capabilities

  • Proof-of-concept prototyping, pilot-scale and unique solids process modeling
  • Powder fluidization and pneumatic conveying tests
  • Silo quaking, thumping, vibration testing, and analysis
  • Flow visualization experiments
  • High accuracy micro-feeding

Physical Modeling: Project Examples

  • Feeding a sticky, cohesive powder at extremely low rates (1 g/minute)
  • Micro-dosing a seasoning mixture uniformly
  • Aligning pharmaceutical tablets in a high speed filler
  • Filling of ammunition cartridges at high speeds
  • Feeding a reactor with biomass with continuous, high accuracy control
  • Operating powder fluidization model at high temperature
  • Testing of large particle bulk solids (e.g., coal and switch grass)

 AnalyticAL Modeling Capabilities

Using proprietary tools developed in-house based decades of bulk material handling research and commercial software such as ANSYS®, we have extensive analytical modeling capabilities.

Discrete Element Method (DEM) simulations of particle flow

  • Transfer chute analysis and design (use of calibrated DEM model)
  • Prediction of absolute wear in transfer chutes and hoppers/silos
  • Hopper analysis and design
  • Rotating equipment (kilns, blenders) analysis

Process Equipment Analysis

  • Particle-gas diffusion modeling for purge column residence time analysis
  • Particle drying analysis for design of direct drying (contact bed) systems
  • Gas-solids models for powder settlement, flow through lock-hoppers
  • Air blaster design tool for selection, location, and usage optimization

Finite Element Analysis (FEA)

  • Stress and deflection calculations for silos, hoppers, and structures
  • Fatigue analysis for connections that are bolted, flanged, and welded
