Only at the start of the year, for example, FL landed a big order for a new copper ore beneficiation installation in Russia with two SAG mills and two downstream ball mills respectively (Fig. 7). These are SAG mills with 12.2 m diameter and 28 MW GMD drive and ball mills with 8.5 m diameter and 22 MW GMD drives.
several MW; for example, the largest installed Isamill has 3 MW installed power.[3] This quantity is small compared to the power used by a semi-autogenous mill and a ball mill in a primary grinding circuit; a ball mill can have an installed power of up to 15 MW, while installed power for a SAG mill can go up to 25 MW.
At the end of 2010, the SAG mill ball size was changed to 10mm but pro5 ved to be unsuccessful, with the mill becoming unstable due to insufficient ball charge and a feed topsize of between 38 mm and 50 mm. A blend of 125/105 mm media was used from December 2010 until March 2011 when the 125 mm media was fully restored as the make-up ball size.
