However, there are cases, usually related to AG/SAG mills, where the quoted EGL may refer to the flange-to-flange length. If the mill has conical ends then the angle of the cones needs to be input. If there are no cone-ends then zero degrees for the cone angle should be input. Note that the model assumes that both ends of the mill are the same.

mill, and there is nothing to prevent a 1:1 aspect ratio mill of, say 10 m dia. x 10 m EGL equipped with a 20 MW motor from being fabricated. Such a mill would have a less arduous environment than, say, a 13.4 m (44-ft) diameter mill. Slurry transport issues then dominate the mill selection, rather than mechanical/structural constraints.
