Abstract
The invention relates to an apparatus and a method for manufacturing clinker, such as cement clinker, in which the majority of the raw materials is present in a hydrous slurry. Initially, the slurry is dried in a gas suspension drier, and the raw materials are subsequently passed to a thermal unit in which the heating of the raw material is effected fairly quickly so that all organic compounds are destroyed in the thermal unit. Subsequent to being heated in the thermal unit, the raw material is directed to the kiln in which it is nodulized and burned into clinker.
