2014-9-10 The failure of the Collahuasi motor was catastrophic and it occurred within months of commissioning. The Collahuasi motor was for a 40 ft SAG mill. The Antamina 38 ft SAG mill was also driven by an ABB motor and the hanger plates had not failed 2021-3-9 Collahuasi Mine Component Failure Analysis Ball mill repair support Ball Mill Gear Failure Analysis Analysis of SAG mill motor drive failures Regrind Mill Refurbishment Project management, inspection and technical services for 2009-10-1 Having related SAG mill throughput to SAG mill power and the ball mill circuit P 80, the data was then reduced to a series of curves representing the relationship between the SAG mill specific power consumption (S.P.C.), which is the SAG mill power draw divided by throughput, and the ball mill P 80 for each UGM.

Collahuasi has a trommel and Escondida, on some of their lines, has trommels. 2016-6-6 The first major commissioning failure on the SAG mill occurred during installation when the mill was inched without adequate lubricant flow, resulting in the 2019-8-23 Metso Outotec oversaw all the major maintenance for the ML-1012 ball grinding mill at the Cordillera mine, where its trunnion and liner trunnion were replaced. Included in the service work was the planning, engineering, construction, preparations, and execution of the project, all conducted under strict quality and safety control. SAG Mill Bearing Failure. Both main bearings on a SAG Mill at a cement factory suffered a catastrophic failure. In addition to analysing data on the service life of the bearings, our engineer inspected the SAG Mill and the failed bearings. Our engineer also performed Finite Element Analysis (FEA) to investigate the design of the bearings and DOÑA INéS DE COLLAHUASI 7 SAG MILL ACE 8 SUCCESS STORY: ANTOFAGASTA PLC MINERA LOS PELAMBRES 9 THICKENER ACE 10 FLOTATION ACE 11. 3 Operational manager Optimization with ACE Stabilization with BrainWave DCS / Control system Goals and limits Information and strategies Set points Process information Set points 2014-12-18 • Antamina´sSAG mill has the worst condition of slurry evacuation in trommel: α = 222 m 3/h/m 2 • Esperanza and Escondida´sSAG mills have high values of α, but they have a screen • Trommel of 40 feet SAG mill of Collahuasi has an high value of α = 172 m 3/h/m 2.

The gap between the model and the real sys-tem is usually closed by prototype testing, however this is not an option for a 42ft Gearless Mill Drive. The ring motor is not self-supported and needs the mill to fix the rotor poles to and it needs the mill foundation to support the stator. Finally you would need a few thousand tons 2021-12-3 SAG Mill Comminution (" SMC ") testwork results confirm the Baptiste material is medium-hard from a SAG milling perspective.

Powerful ABB gearless drives, rated at 15.5 mega-watts each, drive two eight-meter (26 feet) diameter ball mills that grind small pieces of ore at eleven revolutions per minute. However, the plant’s showpiece is the world’s largest gearless mill drive. Collahuasi copper mine is situated in northern Chile, about 180km southeast of the port of Iquique, at an altitude of 4,400m.

Production increased significantly since June 2013, reflecting a strong ramp up, following restart of the SAG mill (closed for 49 days in Q2 2013) and a return to higher grades. H2 2013 production was 91% higher than H1 2013. 2019-5-14 • Collahuasi is located in the Region of Tarapaca in Northern Chile • The operation is located in the high Andes between 3,000 and 5,000 metres above sea level just 10km from the border with Bolivia • Our port facilities are located at Punta Patache which is close to 200km from the minesite and 70km to the south of the city of Iquique 5- 2021-2-16 • 28 MW GMD for a 40' SAG mill • 28 MW GMD for 42' SAG mill Whether it is size or an installation at the highest altitude (4600 m.a.s.l.), ABB’s GMDs are well positioned to contribute to the building of larger and ever more powerful mills. — Leading the gearless mill drive evolution The ABB gearless mill drive (GMD) is the most powerful Mining, SAG Mill, Agnico-Eagle (英语 pdf 参考案例研究) Project Report Collahuasi (英语 pdf 参考案例研究) ABB mine hoisting systems at Longgu (英语 pdf 参考案例研究) Mining, Conveyors, Alcoa, Australia (英语 pdf 参考案例研究) 2019-7-3 Fatigue Failure and Testing Methods 3 1 INTRODUCTION A perusal of the broken parts in almost any scrap will show that a high number of fail-ures occur at stresses below the yield strength of the part`s materials. 2021-11-17 Wonderwall is taking a look back at the bold-faced names we lost in 2021, starting with this music star Michael Nesmith, the musician best known as a
