This must be taken into account when using the above table, which is figured at 100 per cent. The drier shell is rotated separately from the stationary kiln section.To approximate the load acting on the rotary kiln in a steady-state, a static model is taken into consideration. Consequently, dynamic effects as torsion on spokes at start or cascading bed motion are neglected.
