Key Factors in Rotary Kiln Shell Design
The length of each part of a rotary kiln is designed based on the inner diameter (D) of the kiln shell. 1) The length of the kiln head overhanging section (l1): l1= (1.2~1.5) D. As the first section of a rotary kiln, l 1 is better not to be designed too long, or the length of the effective parts of the kiln will have to be shortened.

Energy and Economic Comparison of Different Fuels in Cement …
Energy cost contributes to about 40–50% of cement production cost in Nigeria depending on the production process and type of cement with 1 tonne of cement requiring 60–130 kg of fuel or its equivalent and about 105 kWh of electricity [ 3 ]. Fossil fuels like coal, pet coke, fuel oil, and gas are the primary fuels used in the cement kilns.

The cement kiln
A development of this process is the 'precalciner' kiln. Most new cement plant is of this type. The principle is similar to that of the dry process preheater system but with the major addition of another burner, or precalciner. With the additional heat, about 85%-95% of the meal is decarbonated before it enters the kiln

Cement Production Process | Cement Manufacturing
There are three steps of the high-temperature system: Drying or preheating, calcining, and sintering. The calcining is the core part of the clinker production; the raw meal is weighed and sent into preheater and cement kiln to process clinker. Grate cooler helps to cooler clinker, the cooled clinker is sent to the cement silo for storage.

Cement Plant KPIs: Track & Calculate Metrics
Let's say a cement manufacturing plant has total carbon emissions of 1,000 tons, total water usage of 2 million gallons, and total waste generation of 500 tons. If their production output is 10,000 tons of cement, the calculation would be as follows: Environmental impact KPI = (1,000 tons + 2 million gallons + 500 tons) / 10,000 tons.
