AG mill (autogenous mill) is a medium-free mineral grinding equipment. The raw ore and the coarsely crushed ore are directly fed into the AG mill. No other medium is involved in grinding. Only the impact between the ore is used for self-grinding. The ore larger than 100mm in the AG mill plays the role of grinding medium.

AG mills (or SAG mills with low ball charges) are often used in single-stage grinding applications. Based on their higher throughput and coarser grind relative to AG mills, it is more common for SAG mills to he used as the primary stage of grinding, followed by a second stage of milling.

if you have done proper test work and assumed your work index is as you provided above quickly i can estimate that your sag throughput is around 517 t/h and if the total % of mill charge is 25 % of the total mill volume, then you can assume the following assumption .i.e. mass proportion of grinding body to ore be 15% steel balls and 10 % ore

As an example at the Kalgoorlie Consolidated Gold 2Mines (WA) 36ft SAG mill the variety of Outer Head Liners was reduced from 36 to 18 items and in doing so decreased the time to replace them by 9 hours at an expense downtime saving of regarding U$ 25,000 per hr. In this instance the liners areas are 3.5 t each.

The biggest feature of SAG mills is the large crushing ratio, which can crush and grind the materials to 0.074mm at one time, accounting for more than 20% to 40% of the total product. The crushing ratio can reach 4000 ~ 5000, which is more than ten times higher than that of the ball mill machine and rod grinding machine.
