- the present invention relates to a sludge drying process and the device for carrying out the process, and more particularly to a method and its device for drying industrial, mixed or urban sludge.
- Another solution is initially to dry the sludge and then put in the form of granules that can be stored.
- the drying step is generally carried out by depositing the still wet sludge on a drying bench, the sludge then being traversed by a heated air flow. At the end of this step the sludge is transformed into granules.
- a disadvantage of this type of treatment is that the drying of the sludge with the heated air flow is too long.
