For example, the SAG mill may have 10 MW of power draw available and the two ball mills each of 7.5 MW of power draw available for a total of ratio of 10:15 (1:1.5). The software uses the particular power model (Bond/Barratt, Morrell Mi, etc.) to determine what is the transfer size where the ratio of E SAG to E ball matches the ratio of mill ...

Mill (grinding) - Wikipedia

Sep 23, 2014· Most of our work since 2000 has been in developing grinding mill foundations to avoid vibration and unacceptable deflections. On a recent project for a plant in Peru, the client was told by the mill vendor that there was no need to do a systems (dynamic) analysis on the mill foundations because the mills on that project were gear driven rather than being driven by ring motors (gearless drives).

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 grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol ...

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

Ball Mill - an overview | ScienceDirect Topics

Traditionally, the number of shell lifters used in a SAG mill is equal to twice the number of the feet in the mill shell diameter (e.g., a 34-ft-diameter mill shell would have 68 shell lifters). This is also called a 2-D shell lining. Eliminating some shell lifters increases the volume of charge between the lifters

Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.

7. Full grinding prediction in a SAG mill including slurry phase size reduction. Finally, we consider prediction of the slurry phase grinding using a batch pilot scale SAG mill. The Hardinge mill simulated here has been used in several previous studies [9,18,37,39,40,46,93]. It has dimensions 1.8 m (diameter) x 0.6 m (length).

Semi-autogenous grinding (SAG) mill liner design and ...

SAG mill liners are different from ball mill liners. the diameter and input size of SAG mill is larger than ball mill. And the grinding media are more less than ball mill. The mining materials need to be a part of grinding media. That means the SAG mill should be hard enough to resist the impact from the mining rocks and not be yield or bend.

Selection of Comminution Circuits for Improved Efficiency

The SAG mill pinion energy is determined from the SAGDesign™ testwork results as follows : W SDT = revs (16,000 + m s)) / (447.3 m s) where : W SDT = AG/SAG Specific Pinion Energy from a F 80 of 152.4 mm to a T 80 of 1.7 mm, kWh/ton ground revs = Cumulative number of SAG test mill revolutions to 80% passing 1.7mm m s = SAG mill feed sample ...

Early SAG mills had a diameter of about 32', later increasing to 34, 36, 38 and 40'. At the same time the mill volume also increased. Typically a SAG mill has a much larger diameter compared to its length. Yet the SAG mill of Newmont's Yanacocha mine in Peru is a single stage mill (no ball mill after the SAG mill…

TECHNICAL NOTES 8 GRINDING R. P. King

Typically, a SAG mill based circuit (P80 of 106 to 150 um) has media costs of around A$1/t. Providing the ore is amenable, the use of primary autogenous milling can reduce this cost by 40%. Autogenous milling is typically practiced in association with .
