Then, in the late 1980s when the price of copper rose quickly from a low of $0.62/lb to a high of $1.62/lb, this substantial increase in price further fuelled the industry demand for larger diameter SAG mills, with mill power quickly doubling from 15,000hp to 30,000hp (11,000-22,000kW). As SAG mills grew in size and number, so did the size …

mentioned some case studies of using good liner designs. For example, the initial SAG mill liner was installed using Hi-Hi with a 6. o . contact angle. Mill throughput increased by 11% after the face angle had been altered to a 17. o. angle and then to a 30. o. angle. Currently, the large face angle (typically 20. o . up to 30. o

5 to 50 TPH SAG Mill. Starting as small as 13 feet (4 m) in diameter on 330 HP and as large as 24′ (14.5 m) in diameter on 3,300 HP, the 911MPE Semi & Fully Autogenous Mills tumble crushed ore without iron or steel grinding media. They are used when the crushed ore pieces are hard enough to perform all the grinding.
A high aspect SAG mill had an ID of 6.0. m and the length measured 4.0 m along the central line.. The mill was charged with ore having a S.G. of 2.65 and the load was 40% of the mill volume. The grinding media steel balls occupied 12.2 % of the mill volume.The mill was rotated at 75% of its critical speed, which was 12.9 rpm.Estimate:

Comminution power – geared versus gearless. Posted by Paul Moore on 27th February 2023. It is well known in the mining industry that the biggest mining concentrators, with the highest throughputs and largest mills, have long used gearless mill drives (GMDs). Since their introduction into the market in the 1960s, the GMD installed …
1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powder-like structures. 3.

Ball mill: When the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.
SAG mills can produce a lot of impact if operated with a high ball charge and low filling. Rod and AG mills can produce a lot of attrition and varying amounts of impact and abrasion. Arraying different mills can take advantage of the strengths of …
Semi-autogenous grinding mills play a critical role in the processing stage of many mining operations. They are also one of the most intensive energy consumers of the entire process. Current forecasting techniques of energy consumption base their inferences on feeding ore mineralogical features, SAG dimensions, and operational variables. …
The SAG mill was put into trial operation in October 2016. After about 2 months of trial operation, the cylinder liner plate was cracked to varying degrees, and the overall wear was small. The ...
semi-autogenous grinding process by dynamically modeling the SAG mill-pebble crusher loop to improve the SAG mill throughput. Cleary [8–10] studied the effect of rock particle shape on the dynamic filling and energy utilization in a SAG mill and analyzed the operation status of a SAG mill under different collision conditions through the coll ...
(EGL) SAG mill driven by a 24,000 kW gearless drive. The SAG mill feeds two FL ball mills each 26 ft. in diameter × 40 ft. long (EGL), each driven by a 16,400 kW drive. The SAG mill is one of the largest volumetric capacity SAG mills in the world and represented the first 40 ft. SAG mill in Peru (Garcia & Villanueva, 2013 [1]).
SAG mills grind ore by lifting it and a small amount of grinding media and dropping it inside a horizontal mill. Ball mills are smaller and use a higher concentration of iron balls to pummel the ore. The mills can operate in an open grinding circuit, feeding secondary grinding systems, or in a closed circuit generating a fine product. ...
This paper presents the technical details of the world's first 42 foot diameter 28 MW gearless SAG mill, installed at the Conga copper-gold project in Peru. It explains the challenges and solutions for designing and operating such a large mill, and how it delivers high efficiency and low maintenance costs.
