For some time, the trend in the cement and other pyro-processing industries has been toward larger and more efficient kilns. Since these kilns operate 24 hours per day, month after month, it has been important to conserve power and avoid down time as much as possible. The high degree of efficiency in the mechanical power transmission that has evolved also means that the kiln can roll back due to the large off-center mass of material in the kiln when power failure occurs or at any time the main drive is shut down. Uncontrolled rollback carries the danger of centrifugal explosion of the main drive components since they may be oversped to many times the normal forward speed.
