EDEM Tutorial: Breakage in Cone Crusher

Stephen Cole

Update March 2025 - This is an outdated tutorial guide, for latest tutorials including Taveras breakage please see:

https://community.altair.com/discussion/33339/edem-tutorials

This tutorial refrences an API version of the Breakage model which is no longer supplied with EDEM, recommendation is to review the SAG mill tutorial from the above link to become familiar with Breakage.

Original Post:

Through this introductory tutorial you will learn how to set up and analyse an EDEM simulation that uses the Tavares Breakage Model. This model is in the form of an Application Programming Interface (API) plugin. In this tutorial we will also learn how to use the breakage tool to extend the size distribution and calculate the fines at the post-processing stage. The tool is an EDEMpy script and is in the form of an executable file.

In this tutorial the Tavares Breakage Model is applied to a cone crusher that breaks materials used in mining and other material handling industries.

The main focus is on:

• Creation of breakable materials and geometry.
• Creation of dummy particles.
• Set up the API model in the Creator. (Edit 2025 - API model no longer supplied, please use in-built breakage model)
• Set up appropriate timestep.
• Analyze the results through the Analyst.
• Export of simulation data to a .csv (text) file.
• Setup and run the EDEMPy script and analyze the results.

hi @orange6 this is an older article referencing the API version of the Taveras Breakage Model. Since it was written the breakage model has been integrated into EDEM, you can find the documentation here:

https://help.altair.com/edem/topics/creator_tree_physics/the_tavares_ufrj_breakage_model_r.htm

And a tutorial outlining the updated workflow for a SAG mill here:

https://community.altair.com/discussion/39773/edem-physics-model-tutorial-2100-tavares-breakage-for-sag-mill

The link you refer to no longer exists so I'll edit the post to reove that, the SAG mill tutorial and documentation should cover any requirements. We don't have an updated version of the Cone Crusher case with the latest workflow so you may want to work through one of the other cases first to get to know the in-built model, then look at this tutorial to covert it to the latest workflow.
