<p>A process for manufacturing lightweight aggregate pellets comprises sintering finely divided industrial waste, such as fly ash or enrichment and flotation waste, as basic material in a rotary kiln together with water-saturated binders in the form of sludge or liquid, sprayed onto the basic material before the formation of the green pellets prior to sintering. The spraying is carried out intermittently or continuously by means of, e.g., nozzles.</p> |
