Chopped Fiberglass
SiO₂ with CaO, Al₂O₃, and B₂O₃ · Fiberglass Strands · Chopped Glass Fiber · Glass Reinforcement Fiber
Chopped fiberglass consists of short strands of glass fibers cut from continuous filaments, typically ranging from 1/8 inch to 1 inch in length. The material is lightweight, fluffy, and tends to interlock or entangle, making it difficult to feed and convey. It is non-abrasive but may generate fine dust fibers that can irritate skin and lungs. KWS designs customized handling systems that ensure consistent flow of chopped fiberglass while minimizing fiber damage and airborne emissions.

- Cement and concrete reinforcement additives
Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Loose Chopped Strands, Bulk Fiber, Pelletized Glass Fiber Bundles |
| Bulk Density | 10–25 lb/ft³ (depends on strand length and packing) |
| Flow Behavior | Poorly flowing; prone to bridging, clumping, and matting |
| Abrasiveness | Low glass fibers are smooth but may cause wear over time |
| Corrosiveness | Not Corrosive |
| Dust Potential | Moderate fine fibers can become airborne and cause irritation |
Handling Challenges
- Bridging and entanglement in hoppers and feeders
- Plugging and surging in screw and pneumatic conveyors
- Fiber breakage or degradation during mechanical handling
- Dust and fiber release requiring containment and ventilation
- Static buildup during transfer of dry fibers
Summary
Chopped fiberglass is a lightweight, fibrous bulk material that presents challenges with flowability, entanglement, and dust control. KWS Manufacturing provides engineered conveying and feeding systems—including live bottom bins, shaftless screw conveyors, and specialized feeders—to ensure reliable material flow while protecting fiber integrity.
With expertise in handling fibrous and low-density materials, KWS ensures efficient, safe, and consistent performance in chopped fiberglass handling applications.
