High-Temperature Mesh Belt Sintering Furnace for Retired Wind Turbine Blade Recycling by Shijiazhuang Hongtao Technology Co., Ltd.

As the wind power industry matures, the sustainable disposal of retired wind turbine blades—composed of glass fiber and carbon fiber composites—has become a critical environmental and economic challenge. Shijiazhuang Hongtao Technology Co., Ltd. addresses this need with its advanced High-Temperature Mesh Belt Sintering Furnace, a specialized continuous pyrolysis solution designed for the efficient recycling of these valuable composite materials.

This furnace utilizes a robust, high-temperature-resistant metal mesh belt conveyor system (typically made from SUS314 stainless steel) to transport shredded blade materials through precisely controlled preheating, high-temperature decomposition, and cooling zones. Within the sealed, oxygen-controlled environment, the organic resin matrices are thermally decomposed, effectively separating and recovering high-quality glass and carbon fibers without compromising their mechanical integrity. The system is engineered for continuous, high-volume operation, featuring independent multi-zone PID temperature control (accuracy up to ±1.5°C), an energy-efficient insulation structure, and an integrated exhaust gas treatment system to ensure environmental compliance.

Hongtao’s Mesh Belt Sintering Furnace offers a reliable, automated, and eco-friendly pathway for wind farm operators and recyclers to transform blade waste into reusable raw materials, supporting the circular economy in the renewable energy sector.
