DLT Belt Dryer

The DLT low-temperature belt dryer utilizes low‑grade heat sources such as hot water and waste heat to preheat circulating air via a heat exchanger. A fan then drives the heated air to uniformly penetrate the material layer on the mesh belt, achieving low‑temperature vaporization and dewatering. The equipment employs a closed‑loop internal recirculation dehumidification process, operates at 40–85°C, and is suitable for drying various types of sludge. With stable operation and low energy consumption thanks to waste‑heat recovery, it has become the mainstream technology for linking sludge dewatering with subsequent treatment.
