Particle Impact Energy Variation with the Size and Number of Particles in a Planetary Ball Mill

To investigate the mechanical energy applying to particles in a grinding process using planetary ball mill, impact of was estimated by simulating behavior and balls discrete element method (DEM) under different conditions size number particles, corresponding their variations during milling. As contributing particle breakage, we focused on generated at particle-to-grinding ball/wall particle-to-particle collisions. The affected level single collision collisions respectively, resulting an increase total with decreasing increasing particles. result suggests that milling such as should be adjusted appropriately based variation so can receive large amounts
