    Depending on the kiln's rotational rate, the bed motion in the transverse plane may be characterized as centrifuging, which occurs at critical and high speeds.This is an extreme condition in which all the bed material rotates with the drum wall. Cascading, which also occurs at relatively high rates of rotation, is a condition in which the height of the leading edge (shear
