Depending on mill design, the setpoint may be a compromise between best breakage conditions (high sound level) and limiting liner damage due to ball strikes (low sound levels). For any particular mill filling, there is a mill speed which will maintain the setpoint sound level (and therefore grinding conditions).

Using a SAG mill with Dark iron balls will increase your dust output per ore drastically. The SAG mill and their component dark iron balls are from the mod EnderIO, and while they require quite a few resources (Iron, Coal power, Obsidian, they drastically increase ore output, as well as some ore specific bonus dusts, such as ferrous dust from ...

Jul 18, 2016· Do one for each ore. If you need more than 9, then add another Interface to another side of the SAG Mill (still touching one of the ME devices) and stock the other ores. ME Chests make pretty good subnet storage, and for manually filling things (setting partitions, Matter Cannon, Color Applicator, etc).

ores get crushed = several ore chunks, ore gravel and an ore dust > ore chunks get sent for further crushing to be made into gravels, again also producing an ore dust periodically > ore gravels go into the ball mill and are mixed with water = ore slurry > ore slurry goes to a chemical bath or a filter = dust > dust gets smelted into resources

Combine ABB's variablespeed drive system with advanced process control ABB Ability™ Expert Optimizer for grinding to provide maximum mill control. It can be applied to new or existing AG, SAG and ball mills, powered by either ringgeared mill drives (RMD) or gearless mill drives (GMD).

The power draw of the SAG mill has room for significant improvement. As ball filling in the SAG mill is quite low, additional grinding media would likely increase the processing capacity of the SAG mill; however, the capacity of the ball mill, with installed power .

The rate of change in shoulder angle with the mill filling was not constant at different mill speeds; the rates were measured to be 1° and °/% for 55% and 85% speed, respectively. ... To convert AG to SAG mills 5% (v/v) balls with the sizes between 125 and 80 mm ...

Feb 25, 2019· Rocky DEM has been used to analyse wear rates on the specified SAG mill by simulating rotation and associated particle movement and crushing. This .

If the mill is being periodically recharged with a combination of different sizes, indicate the equivalent weighted average size. The average size of ball nuclei rejected from the mill. nati Average grs of steel (balls) consumed per every ton of ore ground, over a representative period of w

Depending on the mill size the SAG mills draws between 2 MW and 17 MW. The product from the SAG mill is further reduced in size using pebble crushers and ball mills. Hence, typical gold or copper ore requires between and kWh per ton of energy to reduce the particle size.

Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill .

Having a really hard time with Smelterys and Blazing Pyrotheum. Can I get a hand? ... Either use it up or totally remove the Seared Tank. A good way to waste fuel is to overfill the smeltery with sand. ... For sulfur, you probably want to run a SAG Mill. IIRC, nether sulfur ore gives 24 sulfur in SAG Mill with chance of netherrack byproduct. If ...

The mixed ore and sulphide ore are milled together by a second sulphide circuit (S2) following the phase 2 expansion. The third phase of expansion includes construction of a new 16mtpa sulphide concentrator through a single stage SemiAutogenous Grinding (SAG) mill, which can be extended up to 25mtpa by adding a ball mill in the future.

A new primary crusher near the open pit, a new grinding plant (with one SAG mill and two ball mills) at Confluencia, a conveyer tunnel between the mine site and grinding plant, a 52km ore slurry and water reclaim pipe line, and a new flotation plant near the existing plant at Las Tortolas were constructed as part of the project.

an 8 m diameter SAG mill with LID = grinding a copper ore, and predicted maximum capacity and minimum kWh/ton at about 6070 ball load at 25070 total filling. Two FAG mills of LID = 2 were necessary to give the same capacity, and the simulations indicated a lower kWh/ton for these mills. For this ore, both systems were technically feasible.

The three metre by metre gyratory crushers reduce the pit run ore to minus metres in size. Crushed rock is conveyed to three covered stockpiles that feed five parallel grinding lines in the Mill. Primary mills consist of three semiautogenous (SAG) mills and two autogenous (AG) mills.

Knowing the size distribution of ore, thanks to a split engineering image analysis system, the mill optimizes feed size and grinding efficiency. Each grinding line has an 11m diameter by variablespeed Svedala SAG mill. Slurry is discharged to a cyclone feed sump and pumped to .

The selection of controlled and manipulated variables took into account performance and functional criteria. The power draw, volumetric filling level, and a size reduction percentage were the controlled variables, while the fresh ore feed rate, fresh water feed rate, and the SAG rotation speed were the manipulated variables.
