In contrast to laboratory-scale testing for ball mills and AG/SAG mills, test work results for stirred mills can be used for sizing full-size equipment with a scale-up factor close to one. Larson et al.[19,20] found a scale-up factor for the Isamill of exactly 1, while Gao et al. imply that the scale-up factor for SMDs is 1.25.

SAG mill. SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

considered AG/SAG grinding, even if it was not used in the final grinding circuit design. In the 1980s, many of the grinding plants that were built used FAG or SAG mills, and to decrease overall operating costs, many operators of older conventional milling plants considered and actually retrofitted their plants with AG/SAG mills.

This review serves to highlight problems of mill liner designs and how they can be tackled in a logical and often inexpensive manner by considering charge trajectories and liner spacing criteria, in conjunction with liner wear monitoring. Dramatic shortcomings of mill liner designs, especially of large SAG mills, such as rapid failure and even mill shell damage arising from impacting of …

Comparison of HPGR - ball mill and HPGR - stirred mill circuits to the existing AG/SAG mill - ball mill circuits Wang, Chengtie Abstract. In the past 20 years, the energy-efficient comminution technologies, including high pressure grinding rolls (HPGR) and high speed stirred mill, have been developed and adopted in the hard-rock mining ...
1. IntroductionThe main challenge of AG and SAG mills, which is one of the most important technologies in mineral processing industry in recent decades, is its operating time. The major reason of mill shut downs which lowers the mill availability is the time taken for replacement of broken or worn liners.

the mill speed as a fraction of the critical speed, ϕC, can be observed by plotting the process power and torque draw superimposed on the relevant motor capability curve. Such plots for an example mill, the SAG mill at Cadia (described by Dunne et al., 2001) is shown in Figure 3.
Grinding is one of the most important and expensive steps of mineral processing. Therefore, different types of grinding mills such as rod mills, ball mills, semi-autogenous (SAG) mills and autogenous (AG) mills can be utilized for comminution of mineral ores [].Up to today, SAG mills and AG mills have been widely used to reduce operation costs and increase …
Founded by Dr. Karl Gugel, Digital Control Lab started its life in 1998 as an electronics consulting firm known as DiCon Labs. During the early years, DiCon Lab was contacted by a leading cement manufacturer to replace microphone based systems for real-time mill loading measurements. The result was the first generation of MillScan products.

Rod, Ball and Pebble Mills. The products from AG or SAG mills typically feed secondary grinding mills with particles that range in size from 5 cm down to below 100 microns (0.1 mm). The final particle size is determined by downstream processing requirements. Grinding is carried out as a wet process with water content between 50 – 70% by weight.
The SAG Mill is a machine added by Ender IO.It uses Micro Infinity (µI) to grind (or mill) items into their crushed variants, like Ores into Dusts.The SAG Mill has four output slots; recipes can have 1-4 different outputs, with different chances of obtaining those outputs. Uniquely, the SAG Mill can use Grinding Balls made from various materials to increase energy efficiency …
