ABSTRACT:
An installation is disclosed for processing a wet slurry of raw materials for cement manufacture having from 28% to 45% of water, the installation comprising a horizontal centrifugal separator connected to an extruder which produces slugs of partially dewatered material which is then pelletized and fed to a rotary Portland cement kiln. The extruded slugs can be admixed with dry powdery material to prevent their sticking together and to introduce powdery dry material in the kiln.
