The slurry-residue dying machine can quickly dry the slurry-residue with 65% to 75% moisture into the product with only 13% water. Coal (or biomass, natural gas, coal gas) is used as the main fuel to warm the air as a medium. The high-temperature airflow will dry different kinds of materials in a short time. Electromagnetic speed adjustment system is used as a transmission system, along with the automatic temperature controller. The product will maintain the original color, quality, taste and nutrient contents after being dried.
Materials:Widely used for drying slurry, sludge, slag, and residue, etc.
Application:Drying slurry and semi-solid residues for resource recovery.
Wet sludge with about 80% moisture and high viscosity is first pre-dewatered by three-belt filter presses, reducing moisture to 55–60%. It then enters the rotary drum dryer for staged drying.
Inside the drum, the material passes through six zones. In the feeding zone, sludge contacts high-temperature hot air for rapid surface evaporation. In the crushing and cleaning zone, lifting and beating devices break sticky lumps into 20–40 mm granules, forming a material curtain to increase heat exchange while preventing wall adhesion.
In the main drying and secondary crushing zones, the loosened material is continuously lifted and dispersed, with particle size reduced to 10–20 mm (as required) and moisture further decreased. In the enhanced drying zone, dense lifting plates ensure sufficient heat absorption to meet discharge standards.
Finally, in the discharge zone, the drum has no lifting plates to minimize dust, and the sludge exits smoothly with a final moisture content of about 20–25%, completing the drying process.

With strong overload resistance and large processing capacity, it effectively minimizes fuel consumption and overall drying costs per ton.
Adopts co-current drying method, where hot air and wet materials enter from the same side, ensuring high evaporation intensity and high thermal efficiency with low outlet temperature.
Operational parameters can be adjusted according to material properties, forming a stable full-section material curtain for thorough heat and mass exchange.
Features improved feeding and discharging systems to prevent clogging and backflow, along with an optimized internal structure that prevents material sticking and enhances heat transfer.
