Optimization of the performance of basic ­refractory bricks for cement rotary kilns

Refractory performance in the rotary cement kiln is dependent on a combination of mechanisms. Information about the process, as well as improved refractory technologies must be considered in order to extend the service life.

1 Introduction

The global cement industry faces a turning point, and the degree of success in adapting to the changing times will determine its future. Among the challenges for the industry, one can list:

Reduction of energy costs

Replacement of fossil fuels by waste-derived fuels (WDF)

Increase of the share of recycled materials in the composition of the raw meal

Reduction of emission of greenhouse gases

Development of new technologies and practices to ensure a self-sustainable business, with zero environmental and social liabilities

Notwithstanding the fact of being the main source of potential...
