The three gearless mill drive (GMD) systems are the ABB most powerful ever made. The GMD for the 40foot SAG mill has a power rating of 28 megawatts (MW), and the GMDs for the two 28foot ball mills have a power rating of 22 MW. They are the largest diameter and most powerful SAG and ball mills drive systems at the highest altitude installed to ...

A SAG mill is used to grind and crush large pieces of rock into smaller pieces of rock, gravel, or dust. It is commonly used in the mining industry. Q2. How does a SAG mill work? A SAG mill uses a combination of impact and attrition to grind the material. The grinding media in a SAG mill are larger than in a ball mill, and there are fewer of ...

Assuming your ore is AGamenable: 7 TPH to 15 TPH is a comfortably production average for a 13′ x ′ AG Mill. A 13′ x 6′ SAG Mill has a reasonable range of: 20 to 30 TPH for gold ore SAG Ball Mill duty. 25 to 40 t/h for copper porphyry SAG Ball Mill duty. In Single Stage SAG duty, the approximate capacity reduces to only 8 to 13 ...
