How to determine the rotary kiln size and
The size (diameter, length or aspect ratio) of the rotary kiln must be reasonably determined when the newly designed rotary kiln or the old rotary kiln is reconstructedAs the type and size of rotary kiln are different, the unit output index of kiln is also different At present, when determining the size of kiln, it is generally calculated according to the reasonable output index of unit clinker Rotary Cement Kiln Simulator (RoCKS): integrated modeling of preheater, calciner, kiln and clinker cooler Chem Eng Sci , 62 ( 2007 ) , pp 2590 2607 , 101016/jces200701063 Article Download PDF View Record in Scopus Google ScholarComputation of steady state thermochemistry in The (fuel mass flow rate in kg/s) and (secondary air mass flow rate in kg/s) can be recorded from the primary data cement kiln The (primary air mass flow rate in kg/s) is calculated by knowing and 10% excess air to the burner, is calculated G F and also G Pa in Modeling of Rotary Kiln in Cement Industry
