Rotary kiln Cement ABB

Operation of a rotary kiln provides many challenges. You have a very large and heavy steel cylinder containing substantial amount of material which is rotated with a drive system often having two motors. This means that the starting of the kiln requires high toque that can be 2.5 times the full load torque.
