Tue Sag Milling In Australia

SAG Milling in Australia — Focus on the Future . The stone examines the current state of equipment and circuit design, with reference to Australian practice. Following a review of the changes in milling applications over the last 15 years, developments in mill design are examined. Current issues include trunnion versus shell support; drive type and economic analysis for comparison of the

SINGLE STAGE SAG/AG MILLING DESIGN - Metallurgy

East Perth, Western Australia 6004. 2 SINGLE STAGE SAG/AG MILLING DESIGN ABSTRACT Single stage semi-autogenous / autogenous (S/AG) milling has become a common design for a variety of ore types with the advantages of being comparatively low capital cost and flexible for future expansion. The single stage SAG/AG milling option is ideal for starter projects with significant exploration and

SAG Milling in Australia Revised Submission INTRODUCTION This is the third review of SAG milling practice in Australia previous surveys were presented in 1991 Siddall and White and in 1997 Siddall The 1991 review described the early adoption of SAG milling principally by a resurgent gold mining industry which was mainly treating soft oxidised ores of low competence

Evolution of SAG Milling Performance — A

Ernest Henry is located in Cloncurry, north west Queensland, Australia. Both operations started in late 1997, with commercial production achieved in early 1998. Different designs and equipment are in use for both operations, however the evolution of SAG milling performance, although logically related to their specific features, reflect similar trends of consistent increases in throughput. This paper will discuss

Autogenous and Semi-Autogenous Mills -

01/01/2016· In Australia, the number of AG/SAG mills increased from about six in 1984 to more than 40 in the following 5-year period . The number of installations worldwide by mid 1989 was about 471, and presently the number is growing. One of the main interests in these mills is the possibility of eliminating at least one crushing stage from the conventional size reduction processes. Such replacements

Selection of Comminution Circuits for Improved Efficiency

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

Semi-autogenous grinding (SAG) mill liner design

SAG mill liner development draws primarily on practical experience from SAG milling operations supported by computer-based modeling of charge motion in SAG mills and on established good design practice. Liner design needs to respond to the process aspects of mill liner action that are critical to good SAG mill performance, i.e., the impact of shell liners on the grinding action and of grates

SAG Mill Control: It Shouldn't be that Hard | E & MJ

A control strategy recently implemented on a large variable-speed SAG mill at MMG's Century Zinc operation in Australia is shown in the chart (found on pg. 32). In this case, mill speed is the primary manipulated variable used to control mill load. While there is no generic control strategy for SAG milling there is a considerable amount of reusable engineering.
