Although rotary kilns are designed to be used for driving a chemical reaction, an issue that often comes up in the processing of a material is when to draw the excess moisture from the feedstock Many times, there is an excess of moisture that needs to be removed from the material before it is converted in the rotary kiln, and people are faced with a decision buy another piece of equipment.
The use of refractory bricks in the kiln directly affects the operation rate of the cement kiln and the output of clinker. The life cycle of the new dry process cement kiln refractory bricks should not be less than 10 months, and the brick consumption per ton of clinker should be less than 500 grams, otherwise, the reasons that affect the life of the refractory bricks should be carefully.
Rotary kiln combustion chamber, with drive motor and gear box, to avoid piek in concentration we need the correct software Secondary combustion chamber, also called post combustion chamber, with support burner to have 1200 degrees C and a residence time of min. 2 sec. for complete combustion, important for CO and dioxins and furans.

Cement Kilns Design features of rotary kilns. Design features of rotary cement kilns The shell of the kiln is made of mild steel plate Mild steel is the only viable material for the purpose but presents the problem that the maximum temperature of the feed inside the kiln is over 1400 C while the gas temperatures reach 1900 C.
Apr 02, 2019 The purpose of this study is optimizing the air and fuel quantities at kiln considering design parameters of the cement plant by keeping adequate safety factors at each level of calculations to assure that neither production rate nor quality of the clinker vary. Analysis of Heat balance was used to determine the sources of heat loss from the kiln system.
ROTARY LIME KILNS Slides 1 and 2 are the title and outline for the presentation. Slide 3, below, shows a schematic of the exterior of a modern rotary lime reburning kiln. Slide 4 shows a schematic of the interior features of a lime reburning kiln. Rotary lime kilns are large steel tubes that are lined on the inside with refractory bricks.
8 Slide 15 Lime Kiln Heat Rate • Heat rate is a measure of energy efficiency – Units are MM Btu ton CaO or GJ tonne CaO – Often stated as MM Btu ton “product” • Typical range – 5 to 9 MM Btu ton CaO – 5.8 to 10.5 GJ tonne CaO – Lower is better Slide 16 Lime Kiln Energy Balance Components • Drying • Calcining CaCO3 + heat CaO + CO2 • Losses – Heat loss through shell.
