Autogenous and Semi-autogenous Grinding Circuits
pebble crusher. AG and SAG mills are very efficient at making angular particles round. Crushers are very efficient at making round particles angular. So there is a potential synergy from passing hard, rounded pebbles from a AG or SAG mill to a dedicated pebble crusher. The crusher product returns to the AG/SAG mill for further grinding.
SAG Mill Process Control
If the SAG mill is not intended to be the rate-limiting step in a process plant, then it is best to adjust the SAG load (and power) to hold a constant tonnage to satisfy another constraint elsewhere. Underground mines are an example: the hoisting capacity of the mine shaft is the rate-limiting step in the process, and the SAG mill must adapt to ...

PRE-CRUSHING OF SAG FEED: FRIEND OR FOE
The SAGDesign test and design equations give the energy to grind an ore from 80% passing 152 mm to 80% passing 1.7 mm. Since this transfer size is fine enough feed for a ball mill no ball milling inefficiencies will occur. A 5 mm closing screen will deliver this approximate size of SAG ground product to the ball mill.
