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.

The SAG mill (AG mill) has both crushing and grinding two functions. The grinding mode can be divided into dry type and wet type, also known as aerofall type SAG mill and dump type SAG mill. The SAG mill (AG mill) needs less auxiliary equipment, is easy to realize production automation, and the product granularity is relatively stable.

Ball mill: When the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.

Ore processing is a 24 hour operation. Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along ...

Rely on our proven track record of AG and SAG Mill superiority. Since the early 1980s, we have been designing and manufacturing Semi Autogenous Mill (SAG Mill) and Autogenous Mill (AG Mill) under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only.

Control of -SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell, M.S., van der Westhuizen, A.P., & Mainza, A.N. 2009).
