Physical Process/ Pilot Scale

Overview

Physical Process & Pilot Scale Modeling

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.

Examples

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

How we can help you with Analytical Modeling

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
