Case Overview
Full-process acceptance trial case study: customer carbon fiber prepreg waste tested on the ZFS-250. Demonstrates the on-site performance of liquid cooling temperature control and anti-tangle structure on prepreg material.
1. Material and Target
| Material Type | Carbon fiber prepreg scrap |
|---|---|
| Initial Condition | Cut pieces of prepreg containing uncured resin; expired prepreg rolls |
| Material Source | Customer-supplied material for acceptance testing |
| Key Challenge | Prepreg combines resin stickiness with carbon fiber toughness — both the sticking-to-blades and fiber-tangling issues must be solved simultaneously |
| Target Output | Customer acceptance standard (short fiber / powder, depending on customer requirements) |
| Downstream Use | Substitute for virgin carbon fiber feedstock; recycled composite intermediate |

3. Equipment Setup
- Core Equipment: ZFS-250 Carbon Fiber Grinding Machine
- Process Route: Prepreg direct feeding → low-speed grinding → screened output
- Auxiliary System: Liquid cooling & temperature control + anti-tangle structure + fully enclosed dust control
4. Process Highlights
Key Metrics Verified in the On-Site Acceptance Trial
Three items were verified on site: ① whether the machine can run continuously and stably without jamming (anti-tangle performance); ② whether the output is uniform and free of sticky clumps (temperature control effectiveness); ③ whether throughput and output specification meet the target.
Liquid Cooling for Temperature Control & Anti-Sticking
The ZFS-250's liquid cooling system keeps the grinding chamber temperature below the resin softening point, preventing the uncured resin in the prepreg from softening due to heat build-up and sticking to blades or chamber walls.
Stable Anti-Tangle Operation
The specialized anti-tangle structure ensures that continuous-fiber prepreg is effectively sheared and dispersed as soon as it enters the grinding chamber, without wrapping around the rotor shaft — enabling continuous, stable operation.
5. Result Summary
- Output: Uniform short fiber or powder; dry and non-sticky; no clumps
- Acceptance Result: The customer confirmed on site that the output met the target specification
- Applications: Recycled carbon fiber feedstock, SMC / BMC filler, composite intermediate
