· Rotary kilns are an advanced thermal processing tool used to cause a chemical reaction or physical change in a solid material through the application of high temperatures 3 Rotary kilns are commonly used to carry out processes such as 4 Rotary kilns are commonly used to carry out processes such as • Calcination 5
Rotary kilns are a large rotating drum that can be either of the direct or indirect configuration In the direct configuration the kiln can be designed for either co current parallel or counter current air flow As solids pass through the drum the heating medium increases their temperature
Rotary kilns sometimes called calciners or rotary furnaces are used for thermal treatment processes such as calcination sintering pyrolysis and firing as well as for oxidation and treatments can be applied to powders granulates suspensions and green rotary kiln consists of a cylindrical rotating body mounted between stationary

What Happen Inside Rotary Kiln Hadoop Training Chennai What happens inside a rotary kiln how stuff works Cement rotary kiln is the most vital part of a cement factory whose outcome is cement clinker A rotary kiln is a cylinder with a length of around 70 m and a diameter of around 5 m in a factory with a capacity of producing
Reactions in the cement kiln clinkering Understanding Cement General description of the reactions in the cement kiln most of the calcination takes place in the rotary kiln within a moving mass of feed place in seconds rather than the half an hour or so inside a kiln at the same temperature The clinker is in the burning zone for perhaps 10 20 minutes but in this time a lot
Rotary kiln is a rotating cylinder installed at an inclination of 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 x 10 6 kcal/h/m 2
Calciner kilns can accomodate shorter loading % loading = FR W t / L A Where FR=feed ratio kg of material entering the rotary kiln per kg clinker W= clinker production in ton/h A= effective kiln cross area m^2 Volume loading should be typically 7 8% for precalciner kilns and is higher for preheater rotation speed increase heat transfer
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
