With the widespread use of fiberglass materials in construction, automotive, wind turbine blades, composites, and other industries, significant amounts of production waste—such as offcuts, edge trim, and non-conforming products—are generated. This waste not only occupies valuable storage space but also increases disposal costs for manufacturers. As a result, effectively converting fiberglass waste into reusable fine powder has become a growing priority.
To address this challenge, GEP ECOTECH introduces a two-stage grinding solution consisting of the GD dual-shaft shredder and the GX fine grinder. This system transforms bulky waste into fine powder, suitable for in-house recycling or further environmental treatment.
Why a Two-Stage Process?
Fiberglass waste has several challenging characteristics:
- High toughness makes it difficult to crush directly
- Long fiber structures tend to wrap around rotating shafts
- Low bulk density reduces transport and storage efficiency
- High abrasiveness demands superior wear resistance from equipment
A single machine is rarely capable of achieving both high throughput and the desired final particle size—hence the need for a staged processing approach.
Stage 1: GD Dual-Shaft Shredder – Efficient Primary Size Reduction
At the front end of the line, the GD dual-shaft shredder handles fiberglass offcuts, scrap rolls, and rejected parts.
Using a low-speed, high-torque design, the two counter-rotating shafts shear the material against each other, reducing large waste pieces into uniform chips. This step effectively reduces material volume and improves feeding conditions for downstream processing.
Typical output size after the GD shredder: 30–100 mm
Stage 2: GX Fine Granulator – Achieving Fine Powder Output
The pre-shredded material is then fed into the GX fine grinder for secondary size reduction.
The GX grinder uses high-speed rotating blades in combination with stationary blades to generate continuous shearing and impact forces, further refining the fiberglass chips. By selecting different screen sizes, the final particle size can be controlled to meet customer requirements—ranging from coarse granules to fine powder.
Process Flow

- Wind turbine blade producers
- Composite materials processors
- Industrial waste recycling projects
Throughput
Depending on specific requirements, the system can be designed to handle from 1 to over 10 tonnes per hour. The solution is fully customizable based on material characteristics, target particle size, and available floor space, delivering a stable and efficient fiberglass waste-to-powder system.
Material Testing Service
To ensure the solution matches your specific needs, GEP ECOTECH offers a material testing service. Customers can send samples of fiberglass offcuts, scrap rolls, FRP waste, or other composite materials for processing trials. Based on the actual test results, we will provide a detailed report covering throughput, output particle size, and equipment recommendations. This allows you to see the final fine powder output firsthand and make informed project decisions.
