Apparatus and method for drying sludge, in particular sewage sludge, by creating a granulate from the dried product. A mixture of a carrier material consisting of recycled sludge which has already been dried and liquid sludge is fed to a dryer. The dried product is fed to a solids separatorafter the dryerand is stored intermediately in the former in an intermediate container that is placed immediately downstream of the separator.

Method and installation for drying sludge

A process and apparatus for mechanical and thermal dewatering of solid-liquid mixture, particularly industrial and sewage sludges, feeds the sludge to a dewatering device to produce a dewatered material which is then dried in a thermal drier. The dewatered sludge is reduced to a granulate-like structure without any intermediate stage and is then dried immediately afterwards. An apparatus for implementing the process includes a mechanical dewatering device being directly connected to a feed unit to produce a granulate-like structure and which is permanently connected to the thermal drier.
