Slurry drying plant, a method for drying slurry and use of a slurry drying plant

Abstract

Disclosed is a slurry drying plant () comprising a slurry extruder () including a slurry inlet () and conveying means () arranged to convey the slurry through the slurry extruder () and force the slurry out of a plurality of exit openings () of the slurry extruder () to form a plurality of slurry strings (), wherein the slurry strings () are forced out into a drying chamber () in which the plurality of slurry strings () is dried. The slurry drying plant () further comprises slurry heating means () comprising flow means for passing superheated steam past the slurry strings () in the drying chamber (), and inlet pressure detection means () for detecting a slurry inlet pressure at the slurry inlet (). The slurry drying plant () also comprises control means () arranged to control the conveying speed of the conveying means () in response to the slurry inlet pressure. Furthermore, a method for drying slurry and use of a slurry drying plant () is disclosed.
