GFRP Recycling Line
Solution Overview
An end-to-end line turning large FRP waste into high-value powder with automation, low-damage grinding and dust-free closed-loop, ensuring stable output and flexible particle sizing.
01 Direct intake of large waste
Handles large FRP pieces without pre-cutting
02 Uniform feeding
Constant metered feed to prevent jamming and ensure continuity
03 Low-damage grinding
Knife-free kneading grinding preserves fiber properties
04 Dust-free closed loop
Negative-pressure sealed piping with efficient dust collection
05 Controllable particle size
Select 60/100/150 mesh; coarse returns for re-grinding

Core Equipment
| Module | Function / Advantage |
|---|---|
| Dual-shaft shredder | No pre-cut; handles large parts. Low-speed high-torque, anti-winding wear-resistant blades |
| Screw conveyor | Sealed conveying between shredding and grinding; buffer silo to stabilize feed |
| Auto metering feeder | Constant metered feed; prevents overload/idling; >20% efficiency gain |
| Low-speed grinder | Knife-free kneading/extrusion; reduces fiber breakage; achieves ~150 mesh |
| Classifier/Sieve | Vibrating sieve for coarse; air classifier for precision; coarse returns |
| Dust collection | Cyclone pre-separation + pulse baghouse; emissions <10 mg/m³; fully sealed negative pressure |
Automated Full automation; only 1–2 operators
Flexible sizing Switch among 60/100/150 mesh as needed
Eco compliance Negative-pressure sealing with efficient dust collection
Fiber protection Low-damage grinding preserves properties
Ops-friendly Reduced jamming and downtime
Fast ROI Replace virgin fillers, cut material costs
