SAG Mill Circuit Example — Gold Processing SAG mill circuit example for gold processing [image: ()] AG/SAG Mill. AG/SAG mills are normally used to grind run-off-mine ore or primary crusher product. Wet grinding in an AG/SAG mill is accomplished in a slurry of 50 to 80 percent solids. 2D and 3D simulations of particles in a SAG MillGold extraction - QueensMineDesignWikiSAG Mill. SAG Milling breaks down ore through impact breakage, attrition breakage and abrasion. The primary design variables in SAG mills include the aspect ratio and the rotation speed. The rotation should be at a rate at which the ore material falls a maximum distance from the head to the impact toe (refer to Figure 3).AMIT 135: Lesson 7 Ball Mills & Circuits – Mining Mill ...Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1. For fine regrinding in open circuit, the ratio ranges from 1.3:1 to 1.5:1.
