This tutorial decribes how to setup and analyze an EDEM
simulation using the built-in Tavares UFRJ Breakage model.
The Tavares UFRJ Breakage model captures various body breakage mechanisms that occur
during particle collision. They also include catastrophic breakage, using concepts
such as size-dependency in breakage probability, and weakening by repeated stressing
to deliver the final size distribution of the material.
Note: This is an advanced tutorial applicable for EDEM version 2025. If you are not an advanced user of
EDEM, it is recommended to first complete the
Introductory tutorials before completing this tutorial.
Objective
The objective of this tutorial is to:
Create breakable materials
Set up the breakage model parameters
Set up appropriate Time Steps
Analyze the results using EDEM Analyst
Use the post-processing tool
In this tutorial, the Tavares breakage model is applied to a Semi-Autogenous Grinding
(SAG) mill, which is a type of tumbling mill that uses steel balls as well as coarse
ore particles as grinding media. This type of mill is widely used in the mining
industry due to its ability to receive coarser particles and produce a finer product
when compared to secondary and ternary crushers.
Important: You must download the simulation
and associated CAD files before starting the tutorial. To download the
