Critical rotation speed of dry ballmill was studied by experiments and by numerical simulation using Discrete Element Method (DEM). The results carried out by both methods showed good agreement. It has been commonly accepted that the critical rotation speed is .  ### Critical speed

Critical speed depends upon the magnitude and loion of the shaft unbalance, the length of the shaft, its diameter, and the kind of bearing support. Many practical appliions suggest as good practice that the maximum operating speed should not exceed 75% of the critical speed; however, there are cases that require speeds above the critical speed to work correctly.  ### The Effect of the Grinding Charge Trajectory on the ...
