SAG mill power consumption ( Pc) in kW, in 4 grinding circuits (GC1 to GC4) at different % of the fresh feed in the size range −6″ +1″ (−152 +25 mm). It is important to notice that the behaviour shown in Fig. 4 is affected by the dependence of the power consumption on the mill sizes. This fact will be addressed later on in this paper. 3.

That is, the SAG mill produces about 10.76% more than the ball mill in the final product. The average consumed energy at SAG and ball mills to produce one ton of final product was 23.16 kWh/t and 36.05 kWh/t respectively. Thus, the ball mill consumes 12.89 kWh/t, more energy than the SAG mill in producing the final product.

SAG mill. SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

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 TRIO 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 ...

Within comminution circuits, High Pressure Grinding Rolls (HPGR) are increasingly replacing conventional SAG, rod and ball mills for hard rock reduction – owing to their substantially lower energy consumption and potential for significant total cost of ownership reduction. Not only do they require as much as 40% less energy than traditional reduction …

These can include both changes to how mills are operated eg ball load, speed etc but also changes to feed size distribution through modification to blasting practices and primary crusher operation – so-called Mine-to-Mill approach. 3.2 Mine-to-Mill The feed size to AG and SAG mill circuits has been demonstrated to have a significant impact

The required product size distribution is to be 80% passing 100 mesh ...

"Power Use: 80%" means a recipe will only require 80% of its default energy cost to be processed. However, the SAG Mill always works at a set energy usage rate; if a recipe requires less energy, the job will be completed faster. Therefore, 80% Power Use equals 25% faster processing speed. Bonus Output modifies chance-based outputs.

Oct 12, 2017· SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.

Ascot Announces Delivery of Ball and SAG Mills and . The mill building was energized with a temporary 25kV power line which enabled interior and exterior lighting and also the use of critical components such as the overhead crane The foundations for the Ball and SAG mills were prepared with concrete and grout works as well as anchor bolt and sole plate installation

The average of the proportion of (consumed) energy by SAG and ball mills from total consumed energy at mills, was 44.65% and 55.35% respectively. The proportion of SAG and ball mills in producing the final product (particles finer than 74 µm) was 55.38% and 44.62% respectively. That is, the SAG mill produces about 10.76% more than the ball ...

In ball mills when the feeding flow increases, the mineral is discharged faster. However, given the fact that the energy requirements needed depend on the ball charge, the values remain the same even with a change in flow. Consequently, the same amount of energy is used to move a large flow of minerals and the distribution of the product ...
