Principle of SAG Mill operation. SAG is an acronym for semiautogenous 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 ...

Publisher Summary. For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling. Since, semiautogenous grinding (SAG) ballmill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on SAG.

For the first few years, the SAG mill charge was measured during scheduled downtime and the charging schedule updated accordingly. In late 2017, investigations of the comminution circuit concluded that the SAG mill was not consuming its maximum power draw capability when operating at a 14% to 16% ball charge and 68% to 74% critical speed.

Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption is low ...
