Transfer chutes represent a critical element in any bulk solids handling operation. The design of these chutes is based on a combination of past experience, experimental prototyping, empirical rules and unpublished in-house models. Whilst these methods have served industry well, there remains a lack of understanding of the flow behaviour of complex bulk solids, particularly around components that exhibit sharp geometlic changes, and under dynamic flow conditions. Sustained capacity is critical to bulk handling operations and hence there is strong motivation for an improved predictive capability, This paper focuses on the application of three-dimensional DEM to the simulation of coal flow through industrial scale chutes. Models are presented to demonstrate the effect of chute friction and inter-particle propel1ies on capacity. The effect of flow centralisers on belt loading is also examined.
