High Transport Costs, Difficult Passage
Single blades are 50-120 meters long, weighing 15-30 tons, with obvious irregular shapes, requiring on-site volume reduction before entering subsequent processing.
Decommissioned Wind Blade Resource Recovery System
Bringing Decommissioned Wind Blades into a Separable, Usable, Recyclable Resource Recovery Closed Loop
Through enclosed feeding, multi-stage crushing, magnetic separation and impurity removal, refined sorting, grinding, and negative pressure dust collection, decommissioned blades are converted into recycled fibers, granular materials, and FRP powder.
INDUSTRY CHALLENGES
Core Issues in Decommissioned Wind Blade Disposal
Complex Materials, Difficult Sorting
Thermosetting resins, glass fiber/carbon fiber, balsa wood, and metal parts are mixed, requiring stable identification and efficient separation.
Prominent Conflict Between Scale and Environmental Protection
Crushing and grinding processes easily generate dust and noise, requiring enclosed conveying, negative pressure dust collection, and safety protection.
Stricter Policies, Rising Compliance Costs
Decommissioned blade disposal needs to shift from landfill and stockpiling to resource utilization, forming a traceable and standards-compliant treatment system.
PROCESS
Complete Process Flow from Decommissioned Blades to Recycled Powder
Pretreatment and Feeding
After decommissioned wind blades are cut into large pieces, they are fed by metal chain plate conveyors for enclosed, uniform feeding, with fire protection systems ensuring full-process safety.
Coarse Crushing
Large pieces enter the coarse crusher (dual-shaft shredder) and are shredded into approximately 150mm strip or block materials, providing stable feed for subsequent processing.
Magnetic Separation and Impurity Removal
After crushing, materials pass through magnetic separators to remove metal impurities, preventing damage to downstream equipment and ensuring continuous and stable production line operation.
Fine Crushing
De-impurified materials enter the fine crusher (single-shaft fine crusher) and are further crushed to 5-15mm particles or fiber-like materials.
Conveying and Refined Sorting
After fine crushing, materials are conveyed by belt conveyors into the sorting unit, achieving efficient separation of glass fiber, resin matrix, and balsa wood.
Grinding
Sorted materials enter the grinding system, processed through multi-stage grinding into 40-80 mesh FRP powder, meeting downstream recycling requirements.
Finished Product Conveying and Storage
Ground powder is conveyed by screw conveyors into storage tanks for temporary storage, achieving enclosed, dust-free collection of finished products.
Environmental Treatment
Full-process negative pressure dust collection system synchronously collects dust, ensuring workshop environmental compliance.
