Experimental and Discrete Element Model Investigation of Limestone Aggregate Blending Process in Vertical Static and/or Conveyor Mixer for Application in the Concrete Mixture

The numerical model of the granular flow within an aggregate mixture, conducted in vertical static and/or conveyor blender, was explored using discrete element method (DEM) approach. blending quality limestone fine fractions binary mixture for application self-compacting concrete studied. potential augmenting mixer working efficiency by joining its operation to a Komax-type mixer, increase conduct investigated. In addition impact feed height on field cone-shaped examined DEM simulation. Applying approach enabled deeper insight into actions, while relative standard deviation criteria ranked uniformity mixture. primary objective this investigation examine behavior two types blenders and estimate combined action these mixers, explore augment homogeneity i.e., mixing quality, reduce time abbreviate energy-consuming.
