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 the impact of shell liners on the grinding action and
performing SAG mill It is possible in some cases to modify a SAG circuit to force it to perform better but this often takes time much effort and costly modifications In most cases the capital spent on a properly sized SAG mill may prevent production losses that would be many times greater over the extended start up period
The JKMRC has been studying and modelling industrial AG and SAG mills for over 40 years but the ability to simulate the effects of blending hard and soft components on mill performance remains

l sag mill 3d models A SAG mill short for Semi Autogenous Grinding Mill plays a key role in converting large chunks of raw materials into smaller usable pieces during the initial phase of processing Powered predominantly by electricity these machines have
SAG Mill process control classically maintains the SAG mill volumetric filling within a set operating range Typically a SAG mill weight measurement by either bearing pressure transducers or load cells is used as an inferred measurement of volumetric filling To maintain volumetric filling within a set operating range the SAG weight setpoint use for process
SAG mills are distinguished by utilising run of mine RoM feed as grinding media with 5 18% steel balls added to supplement grinding media In recent years RoM Ball mills have started taking
EGL SAG mill driven by a 24 000 kW gearless drive The SAG mill feeds two FLSmidth ball mills each 26 ft in diameter × 40 ft long EGL each driven by a 16 400 kW drive The SAG mill is one of the largest volumetric capacity SAG mills in the world and represented the first 40 ft SAG mill in Peru Garcia & Villanueva 2013 [1]
SAG Mill power draw models are used in mill design and grinding circuit modelling to predict how much power will be consumed by a particular mill geometry and operating configuration This paper will compare SAG mill models by Morrell Loveday using "Power Numbers" published by Barratt and Austin against several published mill surveys
SAG Mill process control classically maintains the SAG mill volumetric filling within a set operating range Typically a SAG mill weight measurement by either bearing pressure transducers or load cells is used as an inferred measurement of volumetric filling To maintain volumetric filling within a set operating range the SAG weight setpoint use for process control requires regular review
The 36′ SAG mill considered is a geometrically scaled up version of the m Hardinge pilot scale mill but with a longer belly length reflecting current SAG mill design preferences The belly

Mine to Mill The feed size to AG and SAG mill circuits has been demonstrated to have a significant impact on throughput with effects such a that illustrated in Figure 7 being commonplace Modifying blast design and primary crusher operation can significantly influence AG/SAG mill feed size hence giving a potentially cost effective way to
The Morrell C model is generally regarded as one of the most accurate tumbling mill power draw models and is ideally suited for this application of estimating fill levels of the SAG mill in real time
SAG mill base power was estimated from pilot plant data at kWh/t the basis was a SABC circuit of 8% ball charge Maximum SAG mill power was determined by deducting the installed ball mill pinion power of kWh/t from the maximum overall circuit power of kWh/t to give
