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.
