Simulation of double-deck vibrating screens based on DEM ‎using PFC3D software

Document Type : Research paper

Abstract

Double-deck industrial vibrating screens are extensively ‎used for solid-solid separation based on particle size. ‎Discrete Element Method (DEM) is a numerical simulation ‎approach that can compute interactions between particles, ‎particles and screen surface and their movement. In this ‎article, the results of simulation of particles classification ‎in a 5-panel banana screen with DEM under PFC3D ‎environment is presented. DEM simulations were ‎performed to study the effects of operating conditions and ‎geometry on classification performance. The results ‎previously reported in literature by other researchers were ‎used to validate DEM predications in current research. The ‎mean relative error of partition curves for screen overflow, ‎middlings and underflow were 38.6 %, 16.9 % and 12.8 %, ‎respectively. Given the close agreement between trends of ‎partition curves in previous and current studies, values and ‎sources of prediction errors, the accuracy of performed ‎simulation is evaluated as acceptable.
