Disc dryers provide an ideal solution for drying municipal and industrial sludge to medium or high dry solids levels. The disc dryer is a continuous operation contact dryer. The dryer vessel consists of a cylindrical shell and end cap, and the vessel is equipped with an external heating jacket. A detachable blade is installed inside the agitator, which is fixed on the agitator with bolts. Both ends of the agitator are supported by external bearings. External installation of the drive system.
The stirrer blades hold a thin layer of product on the heated wall and convey the product to the discharge nozzle along the heated container wall. The steam flows through the counter to the product stream and is discharged through the steam nozzle adjacent to the product feed nozzle. The entrained fine particles re-agglomerate when in contact with the wet feed. The free-flowing powder leaves the dryer through a suitable air-tight lock system. Other drying forms may be pasty, melting, etc.
The disc dryer is more energy-saving and has a high economic added value for sludge treatment. When the material is decomposed, the contact area between the material and the hot air increases, and the hot air can be fully utilized. Moreover, the discharged hot air is reused, which greatly reduces energy consumption. The dried product has a particle size of 1-5mm and has a high calorific value. It can be used as a fuel after a certain treatment.https://www.stordworkshop.com/
