Smart refractory solution for
stress loaded rotary kilns

The concept of a chrome ore free PERILEX® has been confirmed in numerous applications, so that a new, innovative and future-proof basic product for the lining of cement rotary kilns is available now.

1 Introduction

Increasing the service life of refractory bricks is a significant contribution to the efficiency of cement kilns and higher environmental protection, because less refractory material has to be produced, and kiln downtimes in the cement plant can be avoided or at least reduced, with a corresponding reduction of the specific energy consumptions, as well as emissions [1].

For example, the specific consumption of basic refractories dropped from 1.2 kg/t clinker in 1970 to its present value of 0.72 kg/t clinker (Fig. 1). Apart from the increased use of alternative fuels and raw...
