- Description
- The depletion of favourable bulk material deposits in relation to their handleability is prompting the industry to consider mining material that may have comparatively less favourable flow properties. Typically found beneath the water table, less favourable bulk materials typically exhibit an increased clay and moisture content, leading to Wet and Sticky Material (WSM) and problematic behaviours regarding handleability. WSMs are prone to cause problems in all phases of the materials handling stream, which is attributed to the inter-particle and boundary cohesion and adhesion forces. This paper analyses the adhesion of bulk materials onto impact plates under dynamic conditions. A recirculating experimental setup was utilised to gain an understanding of the mode of failure that will be experienced for different wall liner materials, wall liner angles and moisture contents of the bulk material. The main component of this research was a comparative analysis for the Discrete Element Modelling (DEM) technique for WSMs to replicate problematic behaviour of the recirculating experimental system in the simulation domain.
