The flame image of the burning zone in the rotary kiln can be regarded as a high dynamic range color image composed of different regions, which can reflect the flame injection situation of the kiln head burner, burning state of clinker, and temperature information [11]. The feature parameters used to characterize the burning state in the …
Large clinker particles are usually an indication of a possible issue with the kiln cooler crusher, while high levels of fines are usually an indication of unsatisfactory kiln operation. Under-burning or over-burning typically results in too much fine clinker and can often be associated with lower quality.
In Portland cement production, rotary kilns are considered as the core for cement manufacturing plants. At the entry of kiln, grinded and homogenized raw material-comprised of limestone (CaCO 3), alumina (Al 2 O 3), iron (Fe 2 O 3), silica (SiO 2) and a small amount of other minerals-pass through a preheater for initial calcination.Inside the …
The length to diameter ratio of clinker calcining kiln has a great influence on the quality, such as Nissan 2000 tons of calcining kiln L/D now some tend to be shorter design control, in order to design more control in about 10 ~ 11 factories, so beneficial to the improvement of the clinker quality.
Shell Cooling Fans are used to cool the shell, to promote coating formation in kiln burning zone area. Cooler. Clinker cooler serves two main objective of cooling clinker from temperature of about 1350 0C to the temperature (65-150 0C) where it can be handled by conveyors like pan conveyors, chain, Elevators etc. and heat recovery from hot ...
In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At 'A,' the raw meal largely decarbonates; at 'B,' the temperature is 1000 C - 1200 …
