Rod mills speed should be limited to a maximum of 70% of critical speed and preferably should be .Critical speed - WikipediaCritical speed depends upon the magnitude and location of the shaft unbalance, the length of the shaft, its diameter, and the kind of bearing support. Many practical applications 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.to calculate critical speed of ball mill practicalMineral Processing - Milling - Practical Action Figure 1: Swing hammer mill being used for lime milling in Malawi. ....
