Dust emission is one of the main problems associated with the operation of transfer chutes. The design of the transfer chute influences dust generation to a large degree. Due to the very specific design of transfer chutes, sophisticated simulation methods such as the Discrete Element Method (DEM) and Computational Fluid Dynamics (CFD) are necessary to predict the material and airflow in such plants. This paper shows how these methods can be combined with empirical found relations for the diffuse dust emissions in bulk material handling to evaluate the dust generation in transfer chutes. Furthermore, it will be discussed how such analysis can support the design of dust exhaustion plants.
