AG mills (or SAG mills with low ball charges) are often used in single-stage grinding applications. Based on their higher throughput and coarser grind relative to AG mills, it is more common for SAG mills to …

SAG Mill ore hardness kWh/t: Energy required to grind an ore from F80 of 152 mm to T80 of 1.7 mm. ... Ball Mill ore hardness, Bond Ball Mill Work Index of SAG ground ore, kWh/t: …

the specific power requirements (inclusive of contingencies) for SAG milling (9.72kWh/t) allows the SAG mill motor size to be determined (i.e. 20MW). Selection of SAG mill dimensions and operating parameters is a complex problem and suffice it to say here that it is advisable in the design to provide operating flexibility to increase power demand.

The ball charge is a function of the bulk fraction of the SAG mill volume (Jb) occupied by balls; the ore retained in the mill is the result of the volumetric filling which depends on the ore size distribution (specially the % +6″ and the % −6″ +1″), on the rotational speed (N/Nc) and on the solid concentration by weight fraction inside ...

processing. SAG Mills can currently be up to 11.0 m in diameter by 4.6 m wide and are considered more ef-ﬁ cient than Ball Mills. They can substantially reduce the crushing and milling process due to their large capacity and efﬁ ciency. With SAG mills, the mineral is received directly from the primary crusher (not from a secondary and/or ...

A total of 120 t of Cristalino ore was prepared and sent to CIMM, where it was crushed and screened prior to grinding tests. The processing equipment included a 1.83 m (8′) diameter by 0.61 m (2′) length AG/SAG mill equipped with a 20 kW motor, a cone crusher, a 0.91 m (3′) diameter by 1.22 m (4′) length ball mill equipped with a 15 kW ...

SAG mills mimic the same shortcoming. It follows that in order to obtain the speciﬁ c energy (SE) to achieve a certain transfer size, based on the 80 per cent passing value, an inefﬁ ciency factor must be applied to the SE of single stage ball mills, rod mills or AG/SAG mills when calculating power according to the Bond Third Theory method.

design a primary ball mill from a rod mill work index rather than a ball mill index, because the industrial mill will operate over a coarser size reduction range as measured in the rod mill test, which may exhibit different grindability characteristics than would be observed at the ball mill index range. Table 2 compares the typical range of

The Effect of Grain Size on Ball Mill Work Index The Bond ball mill work index is the most commonly used comminution testwork procedure in the Millpower 2000 database, with more than double the number of results of the second most common (the combined drop-weight test methods). The ball mill work index is defined as "the kW-hr per ton to ...

20' EGL SAG mill, a Raptor 900 pebble crusher and two 24' x 39'6" ball mills. Each mill is equipped with a 2 x 8500HP dual pinion drive system. The plant was designed to process 1585 h mtpof SAG feed. From startup, the mill struggled to meet the required production rates. Over time, a major initiative that involved

What's the sag mill. https:// AG/SAG is short for autogenous mill and semi-autogenous mill, it combines with two functions of crushing and grinding, uses the ground …

This index is obtained by a batch grinding test, where two kilograms of ore are ground in a standardised mill setup (10 cm diameter by 30 cm long). The index is obtained by a mathematical ...

SAG Mill ore hardness kWh/t: Energy required to grind an ore from F80 of 152 mm to T80 of 1.7 mm. ... Ball Mill ore hardness, Bond Ball Mill Work Index of SAG ground ore, kWh/t: Crushed Bond BWi testing gives a slightly different result. The SAGDesign test is the only test which measures . BWi on SAG ground ore. This BWi is used to adjust the ...

Four vibrating feeders deliver the ore to the SAG Mill feed belt. SAG Mill discharge is pumped to a primary cyclone(s). Underflow from this cyclone is recycled by …

A 42-ft SAG mill was designed and built for Minas Congas mine in Peru, but never installed. "The rise from 34- to 40-ft-dia. SAG mills was quick, but then stalled," Filidore explained. "Today, we're seeing a lot of 28-ft ball mills. Last month, we sold six 28-ft ball mills and six 40-ft SAG mills.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the …

things. It is incorrect to say, for example, "the ball mill work index is 13 kWh/t and the SAG mill SEC is 5 kWh/t, so the total circuit energy is 18 kWh/t." This example is a real discussion that one of the authors had with a flotation engineer who was confused because of the convention of using the same units for both quantities.

Additional applications of machine learning to SAG modeling put the focus on the control of SAG grinding mill circuits, predicting power consumption [90,91], one of the main concerns of plant ...

includes a Bond Ball Mill Work Index test on SAG ground ore from the first stage of the test.
