    A model is derived where the drag force exerted on the particles throughout the falling period is emphasised. The motion of the particles in a rotary drum is described by three actions: Cascade; Kiln and Bouncing. In this study a horizontal rotary drum was used where both the kiln and bouncing actions have minimal effect, therefore, the focus is on the cascade motion of the particles.
