  • Rod Mill Design & Power Draw

    The following equation is used to determine the power that a rod mill should draw. The Bottom Table lists many of the common size rod mills giving speed, loading and power data. The rod mill motor power is in horsepower at the mill pinion-shaft. For different length rod mills power varies directly as rod length. For difference between new and worn liners increase power draw by Reference Guide Low Voltage Motors Basics of IEC Motors,IEC uses kilowatts, NEMA uses horsepower. And like NEMA, IEC assigns comparable power ratings to standard frame sizes. IEC and NEMA, KW/HP comparisons flow smoothly in smaller ratings. However, in larger sizes, they can vary enough to cause concern in some design applications. An example is the IEC 225S NEMA 364T areas for 4-pole motors.
