## Difference Between Sag Mill vs Ball Mill mech4study

SAG mill make use of steel balls included with some large and hard rocks for grinding These mills utilize the balls in making the large fragments of materials broken into pieces The ball charge of a SAG mill is about 9% to 20%This process takes place inside the large rotating drum of SAG mill which is filled with balls partially Interior of the drum uses the lifting plates These platesThis calculation will estimate the volume percentage of charge in a mill based upon the number of lifters exposed above the mill charge Enter total number of lifters: Nt = Enter the total number of lifters installed in the mill Enter number of lifters exposed: Ns = Enter the number of lifters that are exposed above the mill charge Fractions are acceptable and should be used in the : toolsmillfillingHistory The SAG mill model by proposed by Leonard Austin (1990) was largely based on modifications of earlier tumbling mill models by Hogg & Fuerstenau and F Bond The model uses a kineticpotential energy balance to describe the power draw of a mill charge Many geometric components of the earlier models were fit to empirical relationships measured by AustinAustin SAG model
