The grinding circuit used for processing of gold, platinum and base metal ores typically consists of SAG primary mills, followed by ball-mills. The power drawn by the ball-mills is about the same as that of the SAG mill for high capacity milling circuits. Table 1 is an example of data for this type of circuit.

This ball mill was made for grinding sand and cleaning objects like rusty bolts. It works but takes a very long time to grind sand down, this is because of the size of the balls are too small. Getting larger balls will help. Some professionals that design and manufacture mill for industry helped in the design of the lifter and the correct speed

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.

The target grind size of the circuit varies between the 90-95 percent minus 500 mesh (32 μm) depending on the ore and operating conditions (Rajala et al., 2007). A summary of the comparison of unit circuit energy for each option is shown in Figure 3. Option 3 has much higher media and wear lining costs because two ball mills of 8.8 MW
