Raw Bond Model This is a SAG or AG mill plus ball mill model that estimates the specific energy consumption (E SAG) using the 1979 Barratt equation and the classical Bond work index equation including Rowland efficiency factors The model allows a manual calibration factor on both equations (CF SAG and CF ball respectively) This formula usually gives higher total circuit specific energy

Up until now tumbling mills such as AG/SAG mills and ball mills have had a dominant bearing on the design and economics of comminution circuits However it is commonly agreed that the majority of employed comminution processes are energy intensive and energy inefficient accounting for up to 80% of overall process plant energy consumption and

It is also possible to use the −1″ fraction that shows a positive effect on the SAG mill throughput (the power consumption decreases but the specific energy decreases more) because the mineral goes faster to the mill discharge leaving a greater part of the grinding task to the secondary ball mills

8/25/2014In our recent conversation Prof Alban Lynch was very sceptical about where semi-autogenous grinding (SAG) mills have gone and thinks they have taken us along the wrong track He feels that they may be attractive in terms of high productivity but says that their energy efficiency is poor and I feel that these immense machines are going to turn into very large ball mills
