Rod mills, how they function Mine Engineer.Com

2012-11-26 · 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). Grinding action is by line contact between the rods extending the length of the mill.

Diameter Ratio an overview ScienceDirect Topics

The length to diameter ratio for rod-like molecules and the diameter to thickness for disk-like molecules determine the formation of liquid crystals or mesophases in pure chemical compounds, although anisotropic molecular interactions will modify the transitions. So for a long enough rigid rod molecule, or wide enough disk, the compound will melt from the crystalline state to an oriented liquid, and then to
