But calcination in a rotary kiln is the most expensive and also the investment for its installation is quite high However for the materials like Kyanite which require long soaking at calcination temperature for achieving full conversion the down draft kilns chamber or other batch type kilns may be the most suitable one Almost all refractory raw materials can be calcined in a rotary kiln

rotary kiln 6 The zone method and the Monte Carlo method were used for calculating the radiative heat transfer within the dry process and the wet process in a cement rotary kiln 7 The chemical reactions that take place during clinker formation however were not taken into account and the temperature of the gas phase was fixed at a uniform value

in a rotary lime kiln which is both a chemical reactor and heat transfer device In this project a control strategy was developed for the lime kilns in a Brazilian pulp mill in order to reduce the variability on calcination process and decrease the consumption of fuel This control strategy was developed based on the concept of (Advanced Process Control) with automatic generation of set

Numerical Modelling of the Calcination Process in a Cement

A precalciner kiln system is the basis for this study It normally consists of a preheater a precalciner (also known as a calciner) a rotary kiln and a cooler The kiln feed (i e the raw meal) is heated in the preheater and then sent to the precalciner where typically 85-95% of the calcination takes place Calcination is the process of
