  • What it is the optimun speed for a ball mill formula for calculating ncritical in ball mill

    Oct 19 32 What it is the optimun speed for a ball mill posted in Pyrotechnics I have done a ball mill recenly finished but the motor has too rpms is too fast for use in a ball mill the pvc cylinder that i use left of the shafts With the motor i will use a 40 mm pulley because i have a 50 mm driven pulley in one of my two shaftsformula for calculating ncritical in ball mill PDF THE MODEL FOR OPTIMAL CHARGE IN THE BALL MILL PDF Size of grinding media balls in ball mill strongly affect on specific mill capacity and experiment as well as mill revolution was constant at value 85 of mill critical speed dbmax diameter of the largest ball according to equation 8
