The discrete element method (DEM) is attracting growing attention for the simulation of industrial Bulk solid flow; much of the earlier DEM modelling has considered two-dimensional (2D) flows and used circular particles. The DEM maintains the individual record (velocities, forces, etc.) of particles in flow and stress on equipment. This will enable the designer to know the problems in the design. Transfer chute is used in many industries to facilitate bulk material from one conveyor belt to another or for guide flow from a delivery point (feeder, screw conveyor) into a process or equipment (centrifuge, screener, etc.). Although the transfer chute itself may appear to be a low-cost part of the equipment train, it can easily become costly in maintenance due to plugging, abrasive wear, segregation, etc. The objective of this study is to analyse the stress distribution in a transfer chute when it is in use and to validate design is free from plugging. The modelling was done using the CREO PARAMETRIC software as per Industry standards. The Chute was modelled and simulated using the ROCKY DEM software. In the present research work, a discrete element analysis procedure is used in the ROCKY DEM simulation to predict the level of stress and velocities of particles.
