Recycling background
With the rapid growth of global wind power installed capacity, the issue of handling retired wind blades is becoming increasingly prominent. Wind blades are mainly made of glass fiber or carbon fiber reinforced resin composite materials, which have the characteristics of large volume, complex structure, and difficult degradation. Traditional landfill or incineration methods not only occupy land resources, but also cause secondary pollution to the environment. Therefore, developing efficient and environmentally friendly recycling technologies has become an urgent need in the industry. The mechanical physics method has become the mainstream solution for wind turbine blade recycling due to its simple process, low cost, and environmentally friendly characteristics.
Technological process
The recycling process of wind turbine blades is a systematic and multi-stage process aimed at efficiently converting retired blades into recyclable materials. Firstly, the complete blade is cut into 5-10 meter sections using hydraulic olecranon pliers for subsequent processing; Next, the double axis shredder roughly crushes the section into fragments of 50-100mm to avoid fiber entanglement; Then, the hammer crusher performs secondary crushing on the coarse crushed material to obtain particles of 10-20mm; Afterwards, the grinder grinds the particles to a fine powder of 1-5mm, meeting the requirements of downstream applications.

Core equipment
Hydraulic olecranon pliers
Hydraulic olecranon pliers are used to cut complete wind blades into easily manageable sections. It is equipped with high-strength alloy blades and hydraulic drive system, significantly improving cutting efficiency while reducing manual operation risks.
Double shaft shredder
The dual axis shredder processes blade fragments into smaller particle sizes through low-speed shearing and tearing. Its dual axis design effectively avoids fiber entanglement and material blockage problems, and its high torque characteristics easily cope with the strong bonding properties of composite materials.
Hammer crusher
The hammer crusher further crushes the material through a high-speed rotating hammer head. The hammer head adopts wear-resistant coating technology, which extends the service life and reduces fiber dust emission, thereby reducing environmental pollution.
Pulverizer machine
The grinding machine grinds the crushed particles into fine powder, meeting the particle size requirements for cement kiln collaborative disposal or recycled building materials. Its efficient grinding ability ensures the uniformity and applicability of the recovered product.

Recycling value
Wind blade recycling has significant value and advantages. At the resource level, recycling waste leaves can effectively save raw materials such as glass fiber and resin, reducing dependence on natural mineral resources. In terms of environmental protection, it reduces the environmental pollution caused by waste landfill and incineration, promotes the recycling of resources, and helps promote ecological sustainable development. Economically, the recycling process can create new economic value, promote the green upgrading of the wind power industry and related industrial chains, and provide important support for technological innovation and industrial development in the field of green energy.
