How to simulate a real size distribution?
Hello everyone, I am working on my thesis based on the redesign of a transfer chute located at the first crusher zone within an iron mine. So, I would like to add a shape representation as real as possible to a simplified model simulation that I have already simulate without calibration. I leave attached some extra information. I will be really pleassure to hear your comments.
PD: I have included the media and the sigma for a lognormal representation but the bulk material didn't appear

H,
In EDEM you can set the particle shape and under the Bulk Material > Particle > Size distribution tab there is an option to import a user defined distribution from a spreadsheet. You can set the scale (this is the scale the particle will be created in the simulation relative to the size of the particle prototype you have setup).
Typically I would recommend creating a representative shape of the material (3 spheres is usually good and you can have multiple shapes in the simulation if you need some shape variation) and then creating a size distribution which is close enough to the real size distribution as possible without impacting simulation time too much. Typically this means not directly including the fines but calibrating the material so that the influence of the fines on the bulk material properties is captured through the bulk behaviour.

Hello Stephen,
I have already ran a simulation with your suggestions and it is well working. It is a more realistic size distribution. Now I will research some info about the import option. If you know some of it and could share it, I will really appreaciate.
