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 materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

When fully SAG Milling At The Fimiston Plant excavated the Super Pit will be almost 5 kilometres long, 1.5 kilometres (KCGM+) wide and 0.5 kilometres deep. The Fimiston Plant underwent a major expansion in 1995 which J. Karageorgos (1), J. Skrypniuk (2), W. Valery (3), G. Ovens (4) included the installation of a new 12MW, 36' Fuller SAG Mill ...

SAG Mill Design and Specification . The Kidston plant was designed to process 7500 tpd fresh ore of average hardness; but to optimise profit during the first two years of operation when softer oxide ore will be treated, the process equipment was sized to handle a throughput of up to 14 000 tpd. Some of the equipment, therefore, will become ...

Gearless mill drive (GMD) technology has further expanded the use of large SAG milling allowing Outotec to produce the world's largest SAG mill of 42' in diameter drawing power at 28 MW. Today, Outotec is the world leading supplier of gearless SAG mills operating globally.

Primary crushing followed by wet SAG or AG milling and ball or pebble milling. Air-swept AG milling (for coarse grind). Historically, the lowest operating cost for fine-grained ores was achieved by multi-stage, fully autogenous grinding (Koivistoinen et al, 1989) with integrated magnetic separation steps between the stages.

ROCKY 3D DEM simulations of grinding media flow can be used to investigate the relative performance of comminution devices.

As a production quality index of hematite grinding process, particle size (PS) is hard to be measured in real time. To achieve the PS estimation, this paper proposes a novel data driven model of PS using stochastic configuration network (SCN) with robust technique, namely, robust SCN (RSCN). Firstly, this paper proves the universal approximation property of RSCN with weighted least squares ...

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.,

SAG mill. A semi-autogenous grinding mill, or Sag mill, is responsible for grinding materials from large chunks into small, usable pieces for processing. The Sag mill is usually part of the primary stage in the grinding process. Pieces of raw or fairly reduced materials are ground into smaller pieces for further processing or sorting.
