High Efficiency and Energy Saving: Mainly heat conduction, low heat loss, heat efficiency of 80%~90%, significantly higher than traditional fluidized bed or spray dryer. During the drying process, there is no need for a large amount of hot air, and the air volume requirement is only 10%~20% of that of traditional fluidized beds, which can reduce the energy consumption of fans by 30%~50%. Low exhaust emissions and low temperature, with great potential for waste heat recovery, can further reduce comprehensive energy consumption.

安全性高The sludge is slowly stirred by the blade, creating a low oxygen or micro oxygen environment inside the equipment to eliminate the risk of dust explosion. It is suitable for heat sensitive or easily oxidizable materials such as oily sludge or organic sludge. The drying temperature is controllable, usually between 60~150 ℃, which can avoid the decomposition of organic matter in sludge at high temperatures and the production of harmful gases.

AdaptableThe blade adopts a wedge-shaped or double axis staggered design, which generates shear force during rotation and can effectively break up sludge clumps, avoiding wall sticking or dead bed. It has good treatment effect on high viscosity and high moisture content sludge, such as municipal sludge with a moisture content of over 80% and industrial sludge after chemical treatment. The feed moisture content can reach 85% (liquid)~90% (slurry), and the discharge moisture content is below 10%, which can also be controlled at 30%~50% according to demand.

Low pollution emissionsDue to the low air volume, the concentration of dust and volatile organic compounds (VOCs) carried in the exhaust gas is low. A bag filter and condensing tower can meet the purification requirements, and the equipment investment and operating costs are more than 50% lower than traditional dryers. The overall structure of the equipment is fully enclosed, with no dust leakage, improving the operating environment and complying with occupational health standards.

Compact equipmentModular integrated design, with a volume only 1/3~1/2 of traditional belt dryers, high processing capacity per unit volume, suitable for sludge treatment plants with limited space. The blade is made of wear-resistant alloy material, with a lifespan of up to 5-8 years. The transmission system is equipped with a lubrication system, which has a long maintenance cycle. The blade spacing can be adjusted online or local worn parts can be replaced without the need for complete machine shutdown for major repairs, resulting in low maintenance costs.

Multi functional expansionRaising the heating temperature to 180-200 ℃ can simultaneously achieve high-temperature sterilization and partial pyrolysis of sludge, reducing subsequent stabilization steps. The dried sludge can be used as fuel and co fired with coal, as building materials for making bricks and cement additives, and can also be further pyrolyzed to prepare biochar as a soil amendment, which can meet diverse resource utilization needs.
