Working Principle of a SAG Mill. The rock and grinding media are placed in the mill and rotated, causing the grinding media to tumble and crush the rock into smaller pieces. The mill operates in a closed circuit with screens that size the ore and send it back to the mill for further grinding. The product from the mill is then sent to a cyclone ...

The semiautogenous mill is also called SAG mill which is an acronym for semiautogenous grinding. It is similar to an autogenous mill but uses grinding media like a ball mill grinder. It takes material itself as the main grinding media and grinds through their mutual collision. However, some raw materials with a diameter greater than 20mm and ...

CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

A difference (duty vs. maximum) of 5% to 10% is fairly typical and you would likely struggle to perceive an energy efficiency difference between the two operating points. Beyond this, the situation may change. The 40% vs. 20% is a very large difference in ball charge.

The feed enters one end of the ball mill, and discharges out the other end. Ball mills vary greatly in size, from large industrial ball mills measuring more than 25 ft. in diameter to small mills used for sample preparation in laboratories. Rod mills are similar to ball mills and use metal rods as the grinding media. Pebble mills use rock ...

Or even maybe use the Induction Smelter (tho i have no idea how i would automate that). For mass scale, the pulverizer is probably easier and cheaper, and could be faster when fully upgraded. I like the sag mill for a standalone machine because of the extra outputs. However, the sag mill can also become quite fast without upgrading if you use a ...

Roller mills are mills that use cylindrical rollers, either in opposing pairs or against flat plates, to crush or grind various materials, such as grain, ore, gravel, plastic, and others. Roller grain mills are an alternative to traditional millstone arrangements in gristmills. Roller mills for rock complement other types of mills, such as ball ...

Yes, there is no ball mills in that grinding circuit. The p80 to the SAG mill was at about 6" while its product (flotation feed) was at 40 microns. So the answer to your question is yes, a SAG mill can be installed in an operation milling 2,000 tpd and it can be operated efficiently if the operators have the knowledge to operate it well.

Therefore, SAG mills are favored by large mines and are becoming more and more widely used in the mineral processing industry [1,2]. A SAG mill has low speed and heavy load, which cause the energy consumption of grinding operation to be very high. It accounts for a large proportion of the electrical consumption across the plant .
