Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These

SAG mill A SAG mill is almost always a high-impact application. Hence, it is wise to use tough, impact-resistant materials that are somewhat softer but less brittle to avoid cracking, chipping, or breaking. Rubber/steel composite liners are often a good choice as is the range of more impact-resistant cast alloys. Rod mill As there should be very

SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore. AG mills, on the other hand, are smaller and are typically used for ...

Then, in the late 1980s when the price of copper rose quickly from a low of $0.62/lb to a high of $1.62/lb, this substantial increase in price further fuelled the industry demand for larger diameter SAG mills, with mill power quickly doubling from 15,000hp to 30,000hp (11,000-22,000kW). As SAG mills grew in size and number, so did the size …

Another common issue with SAG mills is operating at very low density (e.g. <70% solids) - if there is room to increase SAG density, this will enable the SAG to grind finer with little or no decrease in throughput. Consider reducing the feed rate when the overload starts rather than waiting until a grind-out becomes necessary. If you are ...
