Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption is low ...

The plus ore will be handled separately and the two will be stored in separate stockpiles. The feed to their SAG mills will be a mix of the two, the plus as media rock and the minus as rock to be ground. The ultimate product from their SAG mill will be about 6 Mesh ( mm). Further grinding will be by ball mill after magnetic separation at ...

SAG mill A SAG mill is almost always a highimpact application. Hence, it is wise to use tough, impactresistant 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 impactresistant cast alloys. Rod mill As there should be very

Since there are not that many small SAG mill operations of under 2000 TPD, and most sub2000 TPD mills are built with rod mills and/or ball mills only; the upstream crusher plant needs to have sufficient crushing power to provide a P80 to grinding of typically <″ (40 mm) and often as finely crushed as <3/8″ (9 mm).

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