Grinding Ball Example. The SAG Mill will process 1 Diamond Ore at the cost of 3,600 µI. It will produce 2 Diamonds, has a 25% chance of producing an auxiliary Diamond, a 15% chance of producing Cobblestone, and a 5% chance of producing Coal Powder. If you use a Dark Steel Ball, then the recipe only needs 70% of the base power, down to 2,520 µI.

A SAG mill is generally used as a primary or first stage grinding solution. Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills. SAG mills are primarily used at gold, copper and platinum mines with applications also .

The throughput capacity and efficiency of a SAG mill are affected by the significant recirculated load derived from over-size discharge product (critical size "pebble" discharge) that is screened out and may be stockpiled or requires secondary crushing prior to re-introduction to the SAG mill feed. Where the SAG mill/ball mill circuit is .

AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit. A diagram of types of AG/SAG .

The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
