The SAG Mill is a machine added by Ender IO.It uses Micro Infinity (µI) to grind (or mill) items into their crushed variants, like Ores into Dusts.The SAG Mill has four output slots; recipes can have 1-4 different outputs, with different chances of obtaining those outputs. Uniquely, the SAG Mill can use Grinding Balls made from various materials to increase energy efficiency (resulting in ...
and a ball mill in a primary grinding circuit; a ball mill can have an installed power of up to 15 MW, while installed power for a SAG mill can go up to 25 MW. However, the energy used for fine grinding is still significant. Moreover, as this paper seeks to demon-strate, large energy reduction opportunities are fre-quently found in fine ...
The primary function of Ball, Pebble and SAG mills is to grind, crush or mix materials into a finer grade of quality as required. Often the use of mill grinding acts as the stepping stone to larger processes which heavily depend upon the refinement of materials or physics related reactions induced by grinding and crushing.
Overland conveyors feed two secondary crushers, and two mill trains each consisting of a 40 foot diameter 28 megawatt SAG mill twinned with a 44 foot length 22 megawatt Ball mill. The grinding mills are amongst the largest of their type currently operating in the world.
SAG and ball mills are generally accepted as the largest power consumers in a mining and mineral processing operation and can be 80% of total electrical energy consumed at a specific power consumption of around 20kWh/ton. Their function is to effect size reduction of rock in order to liberate the target metal compound or compounds trapped in

large geared sag and ball mills. Jaw crushers usually do not work independently, but together with cone crushers, impact crushers, sand making machines, vibrating screens, etc., constitute a complete set of sand and gravel processing systems to achieve accurate processing of ore and rock and improve product pertinence, Increase its market value.
The SAG- Ball mill combination works on impacting and attrition action and the particles residence time increases with its size and density combination. This will generate slimes of high density valuable mineral particle, which is undesired activity and consumes unrequired energy.
Since 1996 this 'Auto-Pilot' system was installed in hundreds of plants to operate mills fully autonomously. The rule-based expert system for SAG, Ball Mills, VRM's and also combined systems secures a permanent optimum production and energy efficiency – without any manual interaction necessity.

A robot system and method have been developed which are able to automatically load balls in semi-autogenous grinding mills so as to reduce the time used for maintenance. The robotic system is comprised of a robotic manipulator of at least 5 degrees of freedom, a grip mechanism which allows, in a sequential and programmed way, to take, manipulate and release a ball …

The SAG mill was designed to treat 2,065 t h −1 of ore at a ball charge of 8% volume, total filling of 25% volume, and an operating mill speed of 74% of critical. The mill is fitted with 80 mm grates with total grate open area of 7.66 m 2 ( Hart et al., 2001 ).
The ideal ball charge volume for a SAG mill is 12% v / v [ 16 ], according to the design objective, and the maximum ball size has a diameter of 150 mm. During operation, however, breakage rates of the shell liners and lifters become extremely high, with a lifespan of only one month when a ball charge volume of 12% v / v was used.
3.5.2.2 Ball Mills. The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as …
Mission South Mill are called SAG (semi-autogenous grinding) mills and ball mills. SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well. To help the process along, eight …
The final plan was to increase the ball charge in the SAG and ball mill to 10% v / v and 27% v / v, respectively; set the upper limit of the operating power in the ball mill to 5800 kW; use a TC Series crusher (without a power-/feed rate–controlling device, but with a feed bin) to crush pebbles for recirculation back to the SAG mill feed ...
… the model accounts for ball charge and load size distribution effects … with the motion of the charge (rocks and balls) in SAG mills … difference between ball mill and sag mill modifying the mill feed size distribution. the sag milling of ores with high levels of competency leads to high sag mill specific power …
The three 28 megawatt SAG mills and four 16.5 megawatt ball mills installed at Cobre Panama are the largest installed anywhere in the world, except for Sentinel.

A SAG mill with a 44′ (13.4m) diameter and a power of 35 MW (47,000 HP) has been designed. [9] Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills.
SAG mill: After primary crusher product of 150mm goes to SAG, and sag product goes to ball mill, then to flotation / magnet separation. The total energy consumed is Primary crushing+ SAG+ Ball mill. * + VERTI MILL: Here secondary crusher product of 4mm goes to HPGR which will reduce to 1 - 2 mm.and goes to vertimill then to flotation / magnet ...
Not surprisingly, some of the advantages of SAG milling are reduced in terms of increased liner wear and increased maintenance costs. Also, pre-crush can lead to an increase in mid-sized material, overloading of pebble circuits, and challenges in controlling recycle loads.
