Abstract

The present paper corroborates, that experimental design technics are applicable to raw mix burnability investigations, and with it the obtained results could cover all the range of possible concentrations of industrial interest. Obtained results agree with theory. A negative interaction was found between lime saturation factor (LSF) and silicate module (Ms) in raw mix burnability and in cement reactivity. In the concentration range studied, working with high LSF and low Ms is recommended.

Highlights

De todas las etapas de! proceso de producción del cemento la más costosa, desde el punto de vista energético, es la fabricación del clinker en el horno rotatorio; la misma consume unos 3.140 kJ/kg de producto terminado [1]
In [7] it was demonstrated that this technics were applicable in this sort of investigation and the objectives of the present paper are the relationships between theory, instrumental technics and experimental design
Six raw mixes were elaborated with different lime saturation factor (LSF), silicate module (Ms), and alumínate module (Ma), that cover the working range of the factory, obtaining the results shown in table 1

Summary

Introduction

De todas las etapas de! proceso de producción del cemento la más costosa, desde el punto de vista energético, es la fabricación del clinker en el horno rotatorio; la misma consume unos 3.140 kJ/kg de producto terminado [1]. Proceso de producción del cemento la más costosa, desde el punto de vista energético, es la fabricación del clinker en el horno rotatorio; la misma consume unos 3.140 kJ/kg de producto terminado [1]. The clinkerization of cement raw mixes, is trie most costly stage in the production of this important construction product, needing more or less 3.140 l
