Kiln shapes are determined based on the variation of the diameter of each section of the kiln shell. Generally, the shape of rotary kiln can be divided into six types: The enlargement of each zone has its own function. For example, rotary kilns with enlarged drying zones increase the heating area of materials during drying, accel…

All sections are welded together. The shell thickness is a result of some calculations, the so-called Kiln Static. Basic for the kiln static are some mechanical rules and some limiting factors for the shell material, the so-called Design Criteria. The design criteria for a kiln shell is the Bending Stress. Different kiln areas have different Loads.
