ABSTRACT:
The invention is related to a method and an installation for preparing cement clinker from carboniferous shale or from any other mineral substance capable of releasing a certain amount of calorific power. According to this novel method, raw material constituted in part by previously calcined carboniferous shale and in part by additive substances which may contain limestone and clay, is submitted to clinkerization. The additive substances are at least partially decarbonated prior to their admixture with the shale.
