An experienced SAG mill operator or metallurgist can recognize the trends in operating conditions associated with various operating states that may impact SAG mill grinding performance.
a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different length to diameter ratios for a given power rating will yield different material ...

Title of Experiment: Ball Mill (variable speed) Objective: To study the operation of a Ball mill and to calculate the efficiency of a Ball mill for grinding a material of known work index (Wi). To study the effect of RPM on the power consumption of Ball mill. To calculate the critical speed (ηc) of a Ball mill. Introduction:
where v = peripheral speed of the mill in feet per minute. If the observed capacity of a mill at speed n1 is = T1 tph, the capacity T2 of the same mill at speed n2 should be . The acceleration factor of the ball or rod mass is a function of the peripheral speed of the mill. Thus. P = f4(F) = f1(D²)·f5(υ) Indicating that υ = πDn, and
