JK Ball Mill Model Notes Review of the JKMRC Mineral Comminution Circuits textbook (Reference 1), and discussions with practitioners of the JKSimMet software have led to the following simplified description of the opera- tion of the JK method for modelling a ball mill.
Modelling: Transfer size limits SAGMILLING.COM
From SAGMILLING.COM. Jump to: navigation, search. The transfer size, T 80, is the characteristic size of the stream between the primary (SAG) and second (ball mill) stages of grinding. It is an important tuning factor for making the circuit work effectively. Contents. 1 How is the automatic T 80 calculated?
Model:Amelunxen SGI SAGMILLING.COM
Of interest is this single-stage SAG mill uses SGI to predict grinding down to about 200 µm with no need for a ball mill work index. The Single Stage SAG model in SAGMILLING.COM uses Amelunxen's form of the equations as it is not normal to reject pebbles the way it is done at El Soldado.
