wet cement kilns based on available commercial technologies. Aspen Plus software package [7] was used for the simulation and preliminary sizing of process units. The process simulation model is expected to provide the following information: product stream concentrations, required liquid feed, and a first estimate of equipment size. This
The technique of thermochemical process simulation has been used to tel for the kiln plant in a cement works which enables the chemical reactions to be calculated in the various process stages.
Computation of steady state thermochemistry in rotary kilns: application to the cement clinker manufacturing process 1. Introduction The technology of rotating drums for heating, drying and calcining has been available for over 100 years. Industrial rotary kilns are used for purposes ranging from drying to
Cement production is a highly energyintensive process, and the rotary kiln is the most important part of the process. Having a comprehensive model of the kiln in order to reduce manufacturing costs, better performance can be created. In this paper, the influence processes in a simulated cement rotary kiln and operating parameters on the output of the study were to develop and validate the
#0183;#32;The key issues governing rotary kiln were discussed in our recent work (Mujumdar et al., 2006) and therefore, are discussed here very briefly. Download : Download fullsize image; Fig. 2. Key issues in modeling cement clinker process.
#0183;#32;10 Wet and Dry Processes: With the arrival of rotary kilns, cement manufacturing processes became sharply defined as wet process or dry process. 1. In the Wet Process, the kiln system is fed with a rawmix in the form of a liquid slurry, typically containing 3050% of water by mass.
Rotary cement kilns can be classified into wetprocess kilns, semidry kilns, dry kilns, preheater kilns, and precalciner kilns. All of these are described in the book by Peray (1986) and many others, hence we will not dwell upon them here.
For the investigation of steadystate and dynamic behaviors of the rotary kiln, first the process variables were defined and then a mathematical model of the process was formulated describing the relationship of those variables. The model essentially represented the material and energy balance at any instant and at any point in the kiln. For this system the equations are firstorder nonlinear

Coating thickness protection in the burning zone of a rotary cement kiln during operation is important from the viewpoint of the kiln productivity. In this paper, an integrated model is presented to estimate the coating thickness in the burning zone of a rotary cement kiln by using measured process variables and scanned shell temperature.
Pyrometallurgical Modelling Kritzinger and Kingsley 51 Modelling and optimization of a rotary kiln direct reduction process Kritzinger and Kingsley Hatch Goba Rotary kilns are used for a variety of mineral processing operations. Hatch makes use of a kiln model developed from first principles to evaluate designs for its clients.
The knowledge of wet process kilns design and operation in the cement industry has not been improved substantially during the last decades since the precalcination process has been developed to become the technological standard. In spite of the tendency to replace wet process rotary kilns for cement production by modern dry process kilns with precalcination, there are still a substantial
#0183;#32;Computer Simulation. A dynamic mathematical model was developed for the simulation and control of cement rotary kilns. The model consists of a set of nonlinear partial differential equations, and represents the material and energy balances in the kiln. Based on some logical assumptions, the model does not only consider the reaction mechanisms but

There are technical diculties in achieving direct measurements of critical process variables in kiln systems. Furthermore, process simulation is used for design, development, analysis, wet process and its modication, (iii) the semidry process, and (iv) conomic analysis of a 4stage dry rotary cement plant and
KilnSimu Rotary Kiln Simulator KilnSimu is used in several industries. Though the technology of rotating drums has been available for over 100 years, it has not been replaced, but remains in active use in many of its traditional applications.
#0183;#32;THE THEORETICAL MODELLING Up to now, most of the mathematical models of cement kilns have been related with the wet process, process which does not need a Lepol grate and in which the water percen#173;tage in the raw material is about 35%.
