AMIT 135: Lesson 8 Rod Mills – Mining Mill

Rod Mill Operations. Designed to accept feed from a secondary crusher. Feed particle size = 6 – 25 mm. Peripheral speed = 85- 146 m/min (280 – 480ft/m in) Reduction ratio = 2 – 20 depending on material. Typically R = 8. Rod Mill Charge: Typically 45% of internal volume; 35% – 65% range; Bed porosity typically 40%. Height of bed measured in the same way as ball mills.

Rod mills, how they function - Mine

Rod mills are very similar to ball mills, except they use long rods for grinding media. 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
