What is a Rod Mill? (with picture) - InfoBloom

A rod mill is an ore grinding mechanism that uses a number of loose steel rods within a rotating drum to provide its attrition or grinding action. An ore charge is added to the drum, and as it rotates, friction between the tumbling rods breaks the ore down into

TECHNICAL NOTES 8 GRINDING R. P. King - Mineral Tech

2009-7-30  8.1 Grinding 8.1.1 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the particles of media - the rods, balls or pebbles ...

Milling Mineral Processing Extractives Hub

Rod Mills are less common and use steel rods instead of balls, whilst Autogenous mills use no artificial Grinding Media but rely on the action of rock-on-rock. Semi-autogenous mills are favoured in modern practice on large mines, using a mixture of balls and rock-on-rock. They are recognisable as having a very large diameter in relation to ...

Rod Mill - an overview ScienceDirect Topics

Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30% of the power used in a ball mill. When they are worn, rods must not stretch but break in rather small pieces, so that they can exit ...

Rod Mill - Shanghai Zenith Company

2021-6-16  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 size of rod mills is about 50 mm (2 in.) while the size range of final powders is between 3000 to 270 mm (4 to 35 mesh).

Mining Infrastructure - Solidworks Design: February

2012-2-16  Rod mills usually require greater operator attention. It is important that the rods stay essentially parallel to one another. If rods become misaligned, grinding action is lost and, more importantly, rod tangles occur. Maximum rod length is limited to about 6.1 m (20 ft). This in turn limits the length, diameter, and capacity of rod mills.
