A sludge dryer has a centrally located rotor having closely fitting blades. It rotates in a precision-machined jacketed shell. The feed sludge is converted into a thin film, which is intensely agitated due to action of the high-speed rotor. The sludge goes through phases of paste and wet powder, before coming out as a dry powder. read more ...

The dried sludge is much easier to store, transport, and package. How Do Sludge Dryers Work? Often a sludge dryer is used for the final drying of sludge or digestate. Dewatered solids enter the dryer's inlet and begin the process of drying as heated air is applied. The airflow moves the dewatered product into a collection system.
