2019-9-27 Attrition mill is a type of grinding mill by kinds of media to crush lump to powder-like substances The impact can be rock on rock such as in an Autogenous Grinding (AG) mill rock and a small ball charge (~10%) used in Semi Autogenous Grinding (SAG) mills balls of various sizes in Ball Mills and less commonly these days steel rods in Rod Mills

MMG was pleased to advise today that the Semi-Autogenous Grinding (SAG) Mill at its Golden Grove operation in Western Australia was back on line The Mill was taken off line in early June due to a failure of the discharge trunnion bearing which the company advised would take approximately 3

While many mills today are mounted on load cells others employ bearing oil pressure as a proxy measurement of mill load A control strategy recently implemented on a large variable-speed SAG mill at MMG's Century Zinc operation in Australia is shown in the chart (found on pg 32)
