Rod Mill Design Calculation EF1 – Dry Grinding – for the same range of work, dry grinding requires 1.3 times as much power as wet grinding EF2 – Open Circuit Grinding – when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced.
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.
