Rotary Kiln Design: Sizing - FEECO International Inc.

When purchasing cement rotary kiln, it is necessary to determine whether its specification is appropriate, rather than blindly select the model. In general, users can get the cylinder size, daily output, rotation speed, motor power, equipment dimension, weight and so on of different types of rotary kiln through the technical parameter information provided by the supplier. We need to select the equipment model based on comprehensive factors such as the property of raw materials, plant size ...

Cement Rotary Kiln - International Cement Review

any persistent red spot covering more than 10% of the kiln circumference (figure-4); Kiln should stop immediately. 3. Kiln alignment conditions: Misaligned kilns induce localized stresses along the kiln length. If the red spot coincides with an area of stress concentration, the shell sometimes elongates or twists beyond recovery. 4. Whether the red spot is exposed or under roof: If the kiln shell is directly
