PROCESS FOR AGGLOMERATING MINERALIFEROUS SLUDGES

1. Process for producing solid agglomerates from compact mineral sludges which contain organic constituents of up to about 10 %, the sludges being formed into formed bodies, the formed bodies being sintered by means of hot gases and subsequently cooled, characterized in that the compact sludge with...

Beschreibung
Zusammenfassung:	1. Process for producing solid agglomerates from compact mineral sludges which contain organic constituents of up to about 10 %, the sludges being formed into formed bodies, the formed bodies being sintered by means of hot gases and subsequently cooled, characterized in that the compact sludge with a water content of 60-30 % is formed into formed bodies by pressing, the moist formed bodies are charged onto a travelling grate, and hot oxygen-containing gases at 500-900 degrees C are passed through the bed of formed bodies until the formed bodies are approximately at the temperature of the hot oxygen-containing gases, but do not exceed a temperature of 950 degrees C, the dry formed bodies are then clinkered with hot oxygen-containing gases of 1 100-1 160 degrees C and the clinkered formed bodies are cooled.
