Mill (grinding) Wikipedia. SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge.

The SAG mill has an inside diameter of m and an effective length of m. The mill operates at 75 per cent of critical speed. It is equipped with six peripheral ports (each 75 mm by 175 mm). Each peripheral port can accommodate a range of grate discharge and pebble port geometry.

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

In fact if one specifies the median size (which in this case corresponds to the maximum frequency) and the spread of the distribution, the entire curve is fully specified. This is the way that most particle size distributions are represented. Almost any real distribution can be approximated in this way, unless it is one that has two or more maxima.
