- Description
- The continuum method is an approach to model transfer chutes characterised by accelerated flow conditions, with origins stemming from free flowing materials. Physical bulk solid properties obtained through laboratory tests are incorporated and the focus is to maintain a rapidly moving stream, with minimum variation in velocity across the burden depth. Due to structural elements, it is difficult to quantify flow occurring inside and as such, accurate site validation is scarce. Discrete Element Modelling (DEM) provides a solution enabling flow visualisation, and a unique means of both qualitative and quantitative analyses. This paper presents application of both methods in a real high throughput installation comprising a bifurcated chute arrangement transferring coal from one delivery conveyor to two receiving conveyors. The results show that both methods can model the type of flow exhibited and presented is a comparison between qualitative site observations and material flow profiles calculated using each method.
