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 …
terms such as "SAG mill inefficiency factor." As ore breakage characteristics can be a major factor in AG/SAG mill product size distribution, Figure 2 compares only data for porphyry ores. Before the true power efficiency of an AG/SAG grinding mill can be properly assessed by using the Wio concept, the T 80 used for calculations must be
average specific power consumption (power at mill pinion shaft) for the AG tests was 10.73 kWh/mt, compared with 12.46 kWh/mt for the SAG tests. The specific power consumption values for both types of primary grinding agreed very well with the results of the simulation work performed by Metso.
It is imperative to ensure the efficient removal of both slurry and coarse pebbles (critical size) in order to ensure the efficient operation of AG/SAG mills. Elimination of the above mentioned material transport problems will allow the mill to respond truly in terms of power draw for changes in mill load which depends on feed ore characteristics.

Maximise ore characteristics and increase productivity with our powerful JK Drop Weight Test - an industry standard for use in characterising ore under AG/SAG milling conditions. The JK Drop Weight Test provides ore specific comminution parameters that are used in the JKSimMet software to analyse and/or predict crusher and AG/SAG mill performance.
Assuming your ore is AG-amenable: 7 TPH to 15 TPH is a comfortably production average for a 13′ x 4.5′ AG Mill. A 13′ x 6′ SAG Mill has a reasonable …
The standard method for sizing secondary ball mills (usually the overflow type) in AG/SAG circuits follows published mill supplier information with aspect ratios in the range 1:1.5 to 1:2.0, depending upon product sizing and pulp flow, i.e., the highest expected circulating loads (Morrell, 2001). The applied net power, calculated from testwork
Accordingly, the mill power consumption decreased from 8.4 to 5.16 kWh/t (a nearly 40% reduction), and the fresh feed flow rate increased from 515 …
Rely on our proven track record of AG and SAG Mill superiority. Since the early 1980s, we have been designing and manufacturing Semi Autogenous Mill (SAG Mill) and Autogenous Mill (AG Mill) under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only.
Self-grinding machine (AG Mi) and semi-self-grinding machine (SAG Mill) are widely used in power, ferrous and non-ferrous metals mineral processing, chemical, building materials and other industries. They grind a certain size of ore or other materials into finer Granularity.

SAG Mill Power. SAG milling can be optimised to achieve maximum breakage and throughput (or any other number of objectives). The relationships between the key variables are highly non-linear and shift as the ore hardness, steel load and liner conditions change.
At the concentration plant of the Gol-E-Gohar Iron Ore Company (Iran) three 9 m × 2.05 m AG (autogenous) mills (fixed speed) are used in parallel in a dry operation.The performance of AG mills has been lower than the target value indicated by an increase in the product size (P 80; 80% passing size) from 450 μm (target) to 515 μm and low power draw (50% of nominal).
in an AG/SAG circuit. This has increased the AG/SAG mills capacity in some cases by up to 25% for an iron ore operation (McIvor & Greenwood, 1996). However, the beneficial gain from crushing critical size material is relatively proportional to the amount of critical size material in the circuit. For example,
