Details+Amelunxen SGI Model. This is a model that estimates the specific energy consumption of a SAG or AG mill plus ball mill circuit using the equation by Amelunxen 2014 for E SAG and the classical Bond work index equation for E ball substituting CF ball in the place of the Rowland efficiency factors.. The model requires manual calibration factors for both equations CF SAG and CF ball
Details+Autogenous Grinding SAG mill in closed circuit with a hydrocyclone package. The gold particle sie distribution data were balanced using NorBal software. The first and second data sets obtained from the two sampling campaigns were used cs curve at its origin and it is a measure of breakage of the ore at lower energy levels.

Details+Which can grind efficiently in a mill c is the exponent which characteries the ball sie distribution. The condition for efficient grinding defined by Eq. 7 will be fulfilled when the grain sie distribution and the ball sie distribution are the same which means that the parameters of both distributions are equal in Eqs. 7 and 9 m c. 10
