We have calculation of rod mill grinding capacity,2215 x 0.931 = 2062 HP. Referring to Table V the3.66 m x 4.88m rod mill with4.72m (15.5 ft.) long rods calculates to draw 972 HP when carrying a 40 percent rod charge with a worn-in bulk density of 5606 kg per cubic meter (350 pounds per cubic foot). 1031 HP is required

May 31, 2016 ROD MILL CAPACITIES. The above tables list some of the most common Open End Rod Mill sizes. Capacities are based on medium hard ore with mill operating in closed circuit under wet grinding conditions at speeds indicated. For dry grinding, speeds and power are reduced and capacities drop 30 to 50%. ROD MILL General Arrangement-Dimensions

Under given load and particle size requirement, capacity is a function of mill length and diameter: Q = kLD 2+N. N is related to mill diameter which decreases with larger diameters k a constant equal to € /4. A chart showing rod mill capacity vs. mill diameter [image: (135-8-5)] A chart showing rod mill capacity vs. mill length

Oct 19, 2015 Oct 19, 2015 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 6%, and adjust for bulk density per Table A. Wet grinding rod mills are normally used in minerals processing plants

The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh)

The liner profile and the stickiness of the pulp in the mill can have a significant effect on the actual critical velocity. Mills usually operate in the range 65 - 82% of
