Working with Vedanta Zinc International's Black Mountain mine in the Northern Cape to enhance safety in its milling plant, Multotec Manufacturing recently designed, manufactured and installed an automated rod charger for the mine's rod mill.
The rod mill rolls steel billets to produce wire rods. This requires accurate, non-contact temperature measurements to produce steel with the desired metallurgical properties. Monitoring the steel rod or wire during rolling, coiling and cooling helps control product quality to ensure a consistent end product.

This machine uses steel rods as the grinding media instead of balls, which are commonly used in ball mills. The rods grind the ore by tumbling within the mill, similar to the action of a rotating drum. Rod mills can be operated at lower speeds than other types of mills, making them ideal for fine and coarse grinding applications. ...
This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge.. Below describes in general terms the Bond Work Index …
Crushing and grinding are the two primary comminution processes. Crushing is a dry process in crushing are-jaw crushers, gyratory crushers and cone crushers. While grinding is generally performed wet in rod mills and ball mills; Our grinding balls have always been active in crushers, ball mill, sag mill and rod mill for the field of comminution.

a. Grinding Mills: Grinding mills, such as ball mills and rod mills, are commonly used for grinding iron ore. These mills contain grinding media (steel balls or rods) that tumble and impact the ore, causing it to break into smaller particles. The choice of grinding mill depends on factors such as the desired product size, capacity …
Relation of Bond ball mill work index and rod mill work index. The Bond rod mill and ball mill work indices are the most similar in size classes, both being fed material crushed to "relatively fine" sizes. Both test are also locked-cycle tumbling tests where the charge of ore in the mill is brought to a steady state over the duration of a test.
mill. As such, primary ball mills should be designed with the rod mill work index, and single-stage ball mills should be with both the rod mill and ball mill indices. This is because it is common to observe a difference (sometimes significant) between the rod mill and ball mill index values for a given ore type (McKen, Verret, & Williams, 2006). On
Rod Mills are similar with the Ball Mills xcept 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 ...
