The drum is basic part of rotary kiln. The rotary kiln drum should have enough stiffness and strength, because the linear of axis and stiffness section were needed during the installation and operation. This rotary kiln drum will affect the life extension of the Rotary kiln lining brick.

    Also the rotary kiln drum is useful for reduce the running resistance and power consumption, reduce the uneven wear, reduce machinery accidents, and ensure the safe and efficient operation for a long time, so the rotary kiln drum is very important. The job of drum stiffness is preventing the radial deformation when rotary kiln drum cross-section faced the large lateral shear. And there are certain requirements to stiffness during transportation, installation and bricklaying. The radial deformation on each point of rotary kiln drum is changed during the operation. If the radial deformation is too large, Rotary kiln will be lead to the internal lining brick loose and affect the service life. Texts showed that the radial deformation of the rotary kiln drum will be max at the fulcrum, and then decreases step by step. the rotary kiln Drum will be cracked under the load effect, especially the part of rotary kiln drum near by the round. There is considerable stress inside of rotary kiln drum, could reached hundreds per cm². And the tangential is much big than axial stress. The rotary kiln drum will be cracked under the joint forces between load effect and welding stress.
