SAG is an acronym for semi autogenous grinding SAG mills are autogenous mills that also use grinding balls like a ball mill A SAG mill is usually a primary or first stage grinder SAG mills use a ball charge of 8 to 21% [6] [7] The largest SAG mill is 42′ in diameter powered by a 28 MW 38 000 HP motor [8] A SAG mill with a 44
Ball SAG and rod mills all require their grinding media to be regularly replaced unlike a HPGR High Pressure Grinding Rolls have lower maintenance overheads than ball and rod mills primarily because the grinding media in conventional mills needs to be replaced on a more regular basis This makes HPGRs more flexible when it comes to meeting
The final plan was to increase the ball charge in the SAG and ball mill to 10% v / v and 27% v / v respectively; set the upper limit of the operating power in the ball mill to 5800 kW; use a TRIO TC Series crusher without a power /feed rate controlling device but with a feed bin to crush pebbles for recirculation back to the SAG mill feed
To prevent a reduction in SAG mill capacity due to a smaller opened area the SAG mill ball charge was increased to 12% Consequently the average mill throughput was 1 572 t/h leveling thus to the first grate combination The third and final combination of third generation grates provided a % open area by using 9 plates of first generation

The screen panel is recognised as the high wear item in the SAG mill trommel While polyurethane screen media is often specified for ball mill trommels Multotec has developed a range of compression moulded rubber compounds that have achieved excellent results in high wear SAG mill duties
For example the SAG mill may have 10 MW of power draw available and the two ball mills each of MW of power draw available for a total of ratio of 10 15 1 The software uses the particular power model Bond/Barratt Morrell Mi etc to determine what is the transfer size where the ratio of E SAG to E ball matches the ratio of mill power 1 in this example
