Rotary kiln is a rotating cylinder, installed at an inclination of 3.5 to 4 % to facilitate material movement. Length and diameter of kiln is decided for the required capacity throughput. Main factors dictating size of kiln are the retention time (25-30 minutes) of material in kiln, degree of filling (10-17%) and thermal loading of burning zone (2.8-4.8 x 10 6 kcal/h/m 2 ).

7) Measurement of Cylinder. The straightness and ovality of the cylinder need to be measured and checked during the examination. The cylinder is the kiln body, it is an important part of the rotary kiln. The straightness and the ovality of the cylinder must always be kept in the normal range, or the rotary kiln will not be able to function stably.

During normal production process, the clinker is always calcined in a fixed temperature range. According to the fluctuation of raw meal composition, the calcination temperature of clinker is generally between 1350℃ and 1450℃. If the temperature in the kiln is too low, it is easy to produce underfired clinker.
