How to Calculate Speed Ratio Sciencing. If you know the speed ration and the speed input you can calculate the speed output using the formula output speed = input speed ÷ speed ratio. For example if you have a speed ratio of 3 and the input gear revolves at 180 rpm work out 180 ÷ 3 = 60. The output speed is 60 rpm. Business offer

The starting point for mill speed calculations is the critical speed. Critical speed (CS) is the speed at which the grinding media will centrifuge against the wall of the cylinder. Obviously no milling will occur when the media is pinned against the cylinder so operating speed will be some percentage of the CS. Ball milling is one of the
