B.4 Modelling and simulation of particulate transport in rotary kiln

  • Jørgensen, Sten Bay (Project Manager)

Project Details


Particulate transport in continuous rotary drums is widely used in the chemical and metallurgical industries. The applications include as diverse areas as mixing, drying and reaction. However no satisfactory model has been proposed for this type of operation and is thus not generally available in standard simulators.
The model development is based upon a detailed experimental study of particle movement in a two-dimensional disk and in rotary cylinders. Upon this basis a nonlinear partial differential equation model is developed for the normal rolling transport of particles. The basic idea is that particles roll on the bed surface, but spend most of the time being transported by rotation inside the particle bed.
This model demonstrates very good agreement with experimental measurements.
