Both the HPGR and the STM vertical stirred mills provide significant energy savings compared to conventional grinding technologies. Our new supply agreement with will enable us to fast track the roll out of an innovative flow sheet using STM mills in conjunction with 's Enduron® HPGR.
comparison to each technology. Both the fluidized stirred mills, the Horizontal Stirred Mill (IsaMill) and the Vertical Stirred Mill (VRMTM) have a scaleup of factor of 1:1 when applied to test work (Larson M 2011, Paz 2019, Paz 2021, Harbort 2016, Gurnett 2019). The reason that the scaleup is 1:1 is that the same feed

It was found that the ball mill consumed 54.67 kWh/t energy to reduce the F 80 feed size of 722.2 µm to P 80 product size of 275.4 µm while stirred mill consumed 32.45 kWh/t of energy to produce the product size of 235.6 µm. It also showed that stirred mill produced finer product than the ball mill at around 40% lesser consumption of energy.
