Carpet Backing
Secondary Backing · Carpet Scrap Backing · Carpet Cushion Backing · Carpet Regrind
Carpet backing is the structural layer attached to carpet fibers and typically consists of synthetic polymers, adhesives, fillers, and reinforcing materials. In recycling and processing operations, carpet backing is often handled as shredded strips, flakes, chips, or regrind. The material can be dense due to high calcium carbonate filler content while remaining flexible and irregular in shape. These characteristics can create challenges with flowability, bridging, and equipment wear. KWS designs heavy-duty conveying systems that reliably handle carpet backing while minimizing plugging and maintenance.

- Composite material production
- Alternative fuel and waste-to-energy applications
Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Shredded Backing, Flakes, Chips, Strips, Regrind |
| Bulk Density | 25-60 lb/ft³ (varies with polymer and filler content) |
| Flow Behavior | Irregular and moderately cohesive; prone to bridging and interlocking |
| Abrasiveness | Moderate to High Calcium carbonate fillers and contaminants can increase wear |
| Corrosiveness | Not Corrosive |
| Dust Potential | Moderate Fine particles and filler dust may be generated during shredding and conveying |
Handling Challenges
- Bridging and material interlocking in hoppers and bins
- Equipment wear from mineral fillers and abrasive contaminants
- Variable feed consistency due to irregular particle shapes
- Dust generation from filler materials and recycled content
- Material buildup and plugging in conventional conveying equipment
Summary
Carpet backing requires conveying and storage systems designed for dense, irregular, and recycled materials. KWS Manufacturing provides engineered solutions—including shaftless screw conveyors, drag conveyors, and live bottom bins—that ensure consistent flow, resist wear, and minimize maintenance.
With extensive experience handling recycled polymers, mineral-filled products, and industrial waste streams, KWS ensures efficient, durable, and dependable performance for carpet backing handling applications.
