Model of particles interaction in rotary kiln

Popis výsledku v původním jazyce

The continuous production technologies based on the principle of rotary drum have been still in the spectrum of interest of process engineers. These equipment are e.g. rotary kiln, drum dryers or drum mixers. Optimization and development of such an equipment is still under the progress. The advantageous tool for these cases is CFD (Computational Fluid Dynamics) simulation. Especially in the moving devices with bad transparency to look inside and with impossibility to directly investigate what happens, the application of the model is fundamental. These simulations allow to investigate the interaction between particles and walls, to uncover the particle moement and to develop technological or construction improvements. The work is focused on the description of the particle movement in the rotary kiln for material production in the field of civil engineering. The objective of the article is to find out the proper but simple model, which will describe the phenomena within the rotary kiln for the production of light building material – KERMAZIT. There are several approaches to describe the behavior of the particle in the rotation cylinder by models. For example DEM (Discrete Element Method), DPM (Discrete Phase Model), DDPM (Dense Discrete Phase Model) or Granular Flow are the most common approaches. The DEM approach was chosen here.
