Where the SAG mill/ball mill circuit is the bottleneck in the processing plant the pebble circuit can be a significant factor in limiting overall plant capacity. The pebble circuit recirculating load can be very significant (depending on the ore characteristics and SAG mill operating dynamics). Typically it represents around 25 % of the feed to ...
Mill (grinding) - Wikipedia
SAG mill. 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%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

in a SAG and Ball mill circuit where there is no scope for storage capacity between milling stages and throughput is normally limited by a bottleneck at one stage or the other. In this case any ore with a high BWi value will have reduced . throughput due to the ball mill despite the capability of the SAG mill to handle
Grinding Circuit - an overview | ScienceDirect Topics
The SAG mill trommel undersize is combined with the ball mills' discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed to the flotation circuit. The designed ball milling circuit product is 80% passing 150 µm.

SABC (SAG mill-Ball mill-Crusher) circuit is the most widely used grinding configuration in large metal mines. It has been proven that reducing the feed size of the SAG mill can improve the energy efficiency or throughput of SABC circuits (Morrell and Valery, 2001). This can be realized by optimizing blasting
