The dried sludge is conveyed in the mixing screw from the dryer return line. Dry and wet are then mixed homogeneously to approximately 45% dry matter and conveyed into the first drying chamber. Using the quickly rotating scoop blades that are fitted to the base of the dryer, the sludge is kept in a constant cloud of material in the air

Fluid bed dryers are widely used for the large scale production of inorganic fertilizers like potash, nitrate, calcium and magnesium, but also for organic fertilizers. TEMA process has a vast experience in the design of dryers for poultry litter, cow dung, dewatered slurry, digester sludge and fermenter waste

Description of Sludge Drying Process. Biomass/sewage sludge from digestion towers or sedimentation tanks is pressed using a de-watering screw or filter press to achieve approximately 25% dry matter. Wheel loaders, conveyor belts, or screw conveyors pass the pressed biomass/sewage sludge into the 1400 ft3 (40 m3) push-floor container of the dryer

sludge dryer drying process principle | rd-dryer

The safety during sludge drying is mainly related to the control of oxygen and dust. The sludge dryer drying process technology does not have dry sludge backmixing. Therefore, there is no dry sludge in the system, the flow rate of the material is small, and the amount of dust is substantially zero
