Home capacity calculation for rod mill

The mill power is also increased by increasing the rod charge and the mill speed, while the mill power and capacity are both increased with increasing mill length. Based on these observations and working on wet overflow mills, Rowland and Kjos [2] suggested that the power draw at the pinion shaft per unit mass of rods is given by (8.6) P M M R ...


Rod mills speed should be limited to a maximum of 70% of critical speed and preferably should be in the 60 to 68 percent critical speed range.
