Numerical study on the impact of particles filling pattern and screw parameters on the mixing uniformity of wheat grains in a screw mixer

The presence of moisture content in a silo makes the preservation grain stock challenging especially when dealing with large stock. This made it as major concern for engineers to preserve crops grains and avoid huge losses. By installing screw inside silo, problem could be avoided by stirring loaded granular bed alongside aeration, also effective mix different types materials. present work has sought develop predictive models discrete element method mixing uniformity assessment wheat granules hopper-bottom mixer. factors being investigated are: initial configuration particles, rotational direction, pitch length, diameter velocity. Findings regarding homogeneity were calculated using nearest neighbor’s method. best mixture was obtained considering side-wise filling type particles ahead 20 mm diameter, 30 rotating at 80 rpm speed.
