SUMMARY
The power required to rotate a horizontal kiln with a mass of 60,000 kg, a length of 35 m, and a diameter of 2.8 m is primarily influenced by rolling resistance and the moment caused by off-center weight. In this case, the rolling resistance coefficient is considered to be 0.005, and the kiln operates continuously at a speed of 4 rpm. While some participants suggested that negligible factors could allow for free rotation, it is established that energy is necessary for mixing feed materials and maintaining production, especially under load conditions.
