Abstract: A large number of particle crushing test results show that there is a noticeable size effect on the particle crushing strength. The particle crushing strength decreases with the increase of particle size. However, the influence of particle shape on the size effect of particle crushing strength is still unclear.

instability has the most significant impact on the crushing strength. The SHAP value demonstrates that flat, rounded, and convex grains have higher resistance to compression. The local roundness at the contact points also affects the crushing strength, in which higher local roundness corresponds to larger crushing strength.
