Abstract
Bulk solids handling is seen in many industrial fields. The dynamics of granular materials in industrial equipment or machinery, such as bins, hoppers, mixers, mills, and conveyors, should be examined in detail to increase efficiency and optimize the specification of machine design. The Distinct Element Method DEM is becoming one of the effective numerical tools to simulate dynamic behavior of granular materials. Shimizu and Cundall conducted a screw conveyor simulation using three-dimensional DEM to examine particle movement inside the conveyor, and compared the results with existing theory and empirical equations. In this paper, we focus on the effect of particle shape, in which non-spherical (i.e., two-pair) particles are used instead of spherical particles in the simulation of a horizontal screw. The results are compared to the findings with spherical particles.
