  • Generally kilns diameter vary from 3 to 6m, and length from 40 to 200m. From maintenance point of view very important parameter is shell thickness: 20mm small shell thickness; 40mm standard shell thickness. There is also some useful parameter of rotary kiln design thickness diameter ratio. For many kiln producers is around 0,6%.

  • Equipment is the foundation of production, rotary kiln is the central equipment of cement production and one of the key points of equipment management.Rotary kiln requirements are round and straight, but due to various reasons in production will occur deformation, resulting in tile heat, brick off and other adverse consequences, but also cause the increase in energy consumption.

  • Rotary kiln shell as rotary kiln’s pillar and rotation part holds on at a high-temperature state under running. Because the rotary kiln shell has joints, which will be burned to deformation. When it gets serious, it will severely damage the normal running of rotary kiln,if the new shell joints do not be switched in time.

  • In order to ensure a long service life of the refractory lining, the kiln shell is optimized for minimum stress and deformation. The shell plate thick- ness changes with corresponding shell stresses, which are determined from bending and tangential shell stress loads.
