Rubber Chunks (Coarse)
Rubber Chunks · Crumb Rubber · Recycled Rubber · Shredded Rubber · Rubber Granules
Rubber chunks are produced from the shredding, grinding, or processing of natural and synthetic rubber products. The material is resilient, compressible, and irregular in shape, creating unique flow characteristics compared to rigid bulk solids. Depending on composition and processing methods, rubber chunks may contain reinforcing fibers, steel remnants, or additives that affect handling behavior. KWS designs conveying systems that ensure reliable flow while minimizing plugging, degradation, and maintenance requirements.

Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Chunks, Granules, Crumb Rubber, Recycled Rubber Feedstock |
| Bulk Density | 20-45 lb/ft³ (depends on particle geometry and composition) |
| Flow Behavior | Moderately free-flowing; irregular particles may interlock and bridge |
| Abrasiveness | Low to Moderate Contaminants and reinforcement materials may increase wear |
| Corrosiveness | Not Corrosive |
| Dust Potential | Low to Moderate Fines may be generated during processing and handling |
Handling Challenges
- Bridging and inconsistent flow caused by irregular particle geometry
- Material buildup and plugging in conventional conveying equipment
- Variable feed characteristics due to mixed recycled content
- Potential contamination from embedded fibers or metallic components
- Maintaining consistent feed rates during processing operations
Summary
Rubber chunks require conveying and storage systems designed for resilient, irregularly shaped materials. KWS Manufacturing provides engineered solutions—including shaftless screw conveyors, drag conveyors, and live bottom bins—that ensure reliable flow while minimizing plugging and maintenance.
With extensive experience handling recycled materials, elastomers, and difficult-to-flow bulk solids, KWS ensures efficient, durable, and dependable performance for rubber chunk handling systems.
