Simulation of charge motion in ball mills. Part 1: experimental verifications

摘要: Abstract A numerical tool known as the discrete element method (DEM) is used to study motion of ball charge in mills. In particular, individual balls simulated. An interesting aspect this simulation that it yields frequency distribution collisions a function collision energy. The results simulations are compared with experiments: angular positions toe and shoulder, trajectory two balls, power draft — all these predictions reasonably close experimental measurements. sidelight can be combined breakage property particles carry out direct particle fragmentation rudiments such illustrated.
