Semi autogenous grinding (SAG) mill liner design and development D. Royston Principal, Royston Process Technology Pty , Brisbane, Queensland, Australia Abstract 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

mills in the older plants that had many mills in parallel. In fact this is generally still the case in the multi stream plants, where mill liner design and selection is only tackled on a cost consumables basis. However, the gains to be had through good liner design and selection are just as great as on the large SAG mills.

Next, the release angle is increased to 35 with 30 high lifters, as shown in Figure 3c. The cataracting charge lands within the toe of the charge. This type of charge motion is ideal for SAG mills in order to preserve the life of shell lifters. The mill speed may be increased without fear of damaging liners.

Graphical abstract. The charge shape and trajectory of the original (face angle 7) and new liners (face angle 30) in the laboratory mill (20% filling). Increasing liner lifter face angle from 7 to 30 increased throughput by 27%. Converting AG to SAG mills by adding 5(%) balls increased throughput by 40%.

For the shell lining optimization solution submitted to TISCO at the beginning of 2016, Zhang Tiebin, the product support manager for mill lining, explained optimizes the charge motion of the material in the SAG mill by changing the lifting angle and height of the shell lining. This way, the direct media to liner impact can be

The three plates enable the lifting profile to be adapted to different operating parameters thereby optimising grinding efficiency. Liners are light plates weighing from 18 24 kg. They are used in mills from 3.0 to 5.4 m diameter. Reference. Royston D, 2007. Semi autogenous grinding (SAG) mill liner design and development.

The mill charge volume has a great impact on grinding efficiency. For efficient grinding, autogenous (AG) and semi autogenous (SAG) mills need to be operated with the correct charge in order to maximize their throughput while avoiding overloading. The Outotec MillSense sensor system gives a precise indication of the mill charge volume.

Charge Height. Generally For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He,

Rod mills. Rod mills are mainly used for primary grinding of crushed ore with a particle size range up to 50 mm for soft materials and between 20 and 30 mm for harder materials where a narrow product size distribution is required (e.g. for subsequent gravity separation).
