A SAG mill is characterized by its large diameter and short length. It rotates, tumbling its contents violently, causing a breaking action. The mill is lined with wear resistant steel liners which are fitted with lifters to assist with raising the load.
done in a SAG/ball mill circuit with no coarse recycle classification of the SAG mill discharge. The primary grinding mill is an 18 ft. diameter x 9 ft. EGL, 1500 HP variable speed SAG mill and the secondary mill is a 13 ft. diameter x 21 ft. long, 2000 HP fixed speed, ball mill.
The total power needed for the ore grinding in the primary SAG mill and the two secondary ball mills for the Esperanza Project was nearly 60,000kW. The SAG mill motor rating is 22.4 MW and each ball mill is 18.6 MW.
1.. IntroductionIt is generally recognised that the most accurate means for predicting the specific energy of an autogenous (AG)/semi-autogenous (SAG) mill circuit is to pilot the circuit using a 6 ′ × 2 ′ mill (Mosher and Bigg, 2001).However, one of the major drawbacks of this approach is that a relatively large sample is required to do so.
