Rod mills are very similar to ball mills. The rods grind the ore by tumbling within the mill. To prevent the conditions leading to rod charge tangling theratio of length to diameter is maintained at 1.4 to 1.6. The maximum input sie of rod mills is about 50 mm 2 in.
Rod mills, ball mills, autogenous mills, and semi-autogenous mills (SAG Mills) all have a number of lubricating and hydraulic systems, and they must work to keep mineral output high. The mill systems oil is subject to extreme levels of very fine particles, and many operators believe the plant should be shut down periodically to change the oil.
The output of 200-series stainless steel rose 164,000 mt on the month as mills in Fujian and Guangxi resumed production. The output of 300-series stainless steel rose 140,000 mt or 11.3% on the month as a mill in Guangdong resumed production in mid-November and mainly produced 300-series products.
The plant's output changed qualitatively. In 1968-70, the plant switched to production of the 6001-6008 series ball and rod mills. Thanks to the use of elastic couplings instead of gear couplings, and the application of self-aligning spherical bearings in roller mills, the durability of these assemblies increased 1.5 to 2 times.

Effect of Operating Variables on Material Transport through Rod Mills. Effect of feed rate on holdup: Figure 8 presents the effect of feed rate on holdup in the rod and ball mills. In the ball mill, the holdup is generally lower than that in the rod mill at corresponding feed rates. As is clear from Figure 8, the maximum feed rate to the ball ...
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 ...
The internal diameters of both rod and ball mills were 2.5 m and a throughput of 100 t/h was initially expected. Estimate the total energy and power required for grinding by the rod and ball mills. The standard laboratory work index of the ore was 12.5 kWh/t.
