Ball Mill Design - freeshell.org

2016-11-18  Once you know the ideal speed of rotation for your mill jars, you will need to design your mill around this critical parameter. With most ball mill designs, you have two areas of speed reduction to tweak: from the motor drive shaft to the drive pulley and from the roller bar to the milling jar. The drive train calculator featured on this page gives you a simple way to play with these numbers and find the dimensions you need. The numbers you enter are not tied to specific units (inches vs centimeters) but you must be consistent in the units you choose to use. Do not enter some numbers as measured in CM and other measured in inches. All numbers are assumed to be using the same units otherwise the calculations will be wrong. Start by entering the dimensions that are the most difficult to change, such as the jar diameter and the roller bar diameter. You can only solve for one number in the table, so five out of the six fields must contain a value before hitting the "calculate" button. Filling all four diameter fields and leaving the motor RPM blank will help you determine the ideal motor for your mill.
