Rubber Powder
Ground Rubber · Micronized Rubber · Recycled Rubber Powder
Rubber powder is produced by grinding natural and synthetic rubber products into a fine particulate material. The material is commonly generated from recycled tires and industrial rubber products and is used as a feedstock in a variety of manufacturing applications. Rubber powder is lightweight, compressible, and prone to dust generation, making containment and flow control important considerations. KWS designs conveying systems that provide reliable material flow while minimizing dust emissions, product degradation, and maintenance requirements.

Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Fine Powder, Micronized Rubber, Recycled Rubber Feedstock |
| Bulk Density | 20-35 lb/ft³ (depends on particle size and composition) |
| Flow Behavior | Moderately cohesive; may bridge or compact under pressure |
| Abrasiveness | Low to Moderate Contaminants and reinforcement residues may increase wear |
| Corrosiveness | Not Corrosive |
| Dust Potential | High Fine rubber particles require containment and dust control systems |
Handling Challenges
- Dust generation and housekeeping requirements
- Bridging and inconsistent flow in hoppers and feeders
- Material buildup and compaction during storage
- Potential contamination from embedded fibers or metallic residues
- Maintaining consistent feed rates in processing operations
Summary
