The current straw micro-crusher is often utilized within a circular crushing chamber, leading to the formation of a circulation layer that impacts the efficiency of crushing. This study proposes an airfoil crushing chamber to disrupt the circulation layer and modify particle motion characteristics. Based on CFD-DEM analysis with flow field characteristics, motion trajectory, crushing rate, motion speed, and force magnitude as evaluation indices, the crushing performance and flow field distribution of both chamber types are compared. Test results indicate that the airfoil crushing chamber outperforms the circular one, thereby validating the accuracy of the theoretical and numerical analyses.
