Three (3) SAG mills per train, installed in parallel, will reduce ore size to a P80 of about 800 microns. Each SAG mill is designed for a fresh iron ore feed of 1,755 t/h. The calculated required power for each SAG mill is 23.5 MW. The SAG mill dimensions are 12.2 m (40 feet) diameter and 7.6 m equivalent grinding length (EGL), which is the ...
Energy costs for grinding corn typically range from 15¢ to 25¢ per ton but can increase to a range of 70¢ to $1.40 or more per ton when fine grinding. It is important to remember that properly maintaining grinding equipment can save the feed mill roughly $50,000 a year in electrical cost when producing approximately 500,000 tons of feed ...
The specific energy per ton of iron was determined according to the feed flow rate (2500 t/h) and the iron concentration in Thanatia (3.63% iron). After the start of the classifying process in comminution, high-iron-content minerals are separated from the unwanted minerals because of their higher specific gravity (SG) and magnetic susceptibility.
