Rotary kilns are widely used in chemical, food, metallurgy and other industries due to small footprint, continuous, stable work and large capacity [1, 2], which are usually designed to be slightly inclined axially or horizontally with a helical pushing mechanism inside, in order to achieve the purpose of the material moving in the axial direction inside the equipment.

The size of a rotary kiln is not only a function of capacity, but also of the quantity of heat which can be generated inside the rotary kiln from the volatizing and / or combustion of the material. The diameter and length of the rotary kiln are calculated based on the maximum feed rate, the needed retention time, and the bed profile (how full ...

Hazardous waste output in the world is increasing every year. To achieve higher efficiency and lower pollution, the incineration technology for hazardous waste needs to be studied further. This study mainly reviews the research progress in incineration, slagging, and pollutant emission in the rotary kiln in China and abroad in the last 10 years, and conducts a …

Standard rate of production (tube capacity) of a rotary kiln is considered 5 times of its effective volume for a day. The rate is fix at hot meal entering kiln with a degree of calcination stated to be above 90%. Like a kiln Ø 3 x 45 m with an insulation thickness 180 mm is expected to produce 1232 mt/day.

The stable operation and management of rotary kiln incineration facilities are very important, and they still face severe challenges. For instance, the production capacity of current facilities is generally unsatisfactory, owing to factors such as unstable operating conditions, unskilled work operations, low level of equipment operation and maintenance, and …
