Case Overview
Full-process case study: glass fiber composite fabric waste crushed to 2 mm short fiber on the ZFS-250. Demonstrates the anti-tangle structure and low-speed shearing process on tough woven fabric.
1. Material and Target
| Material Type | Glass fiber composite fabric scrap |
|---|---|
| Initial Condition | Woven glass fiber fabric pieces / strips, containing resin or coating; flexible and hard to tear |
| Material Source | Customer-supplied material |
| Key Challenge | The glass fiber fabric is both flexible and highly tough — conventional crusher blades struggle to cut the fibers cleanly, causing fabric pieces to wrap around the rotor shaft and jam the machine |
| Target Output | 2 mm short fiber |
| Downstream Use | Chopped fiber reinforcement filler, feedstock for nonwoven mats, reinforcement for molded composites |

3. Equipment Setup
- Core Equipment: ZFS-250 Glass Fiber Grinding Machine
- Process Route: Glass fiber fabric direct feeding → low-speed shearing & crushing → screened 2 mm short fiber output
- Auxiliary System: Anti-tangle structure + dust-collection interface
4. Process Highlights
Anti-Tangle Design Is Critical
The woven structure of glass fiber composite fabric makes it highly prone to wrapping around the rotor shaft during crushing. The ZFS-250's specialized anti-tangle structural design — 'scissor-type' moving blades combined with a reverse control system — cuts the fabric layer by layer rather than pulling and wrapping it, solving the jamming problem at the source.
Controlled Size Reduction to Fiber Level
The target is 2 mm short fibers rather than powder, so the crushing intensity must be precisely controlled — it must fully open the fabric structure down to the fiber level, while avoiding over-crushing that would shorten the fibers too much and reduce reinforcement performance.
5. Result Summary
- Output: Uniform short fibers ~2 mm in length; fabric structure fully opened, no tangled clumps
- Fiber Properties: Glass fiber individual filaments are separated, retaining reinforcement skeleton functionality
- Applications: Feedstock for nonwoven mat production, chopped-fiber reinforcement for molded composites, thermal insulation materials
