Mulch
Wood Mulch · Bark Mulch · Landscape Mulch · Organic Ground Cover
Mulch is an organic material typically produced from wood, bark, leaves, or other plant-based feedstocks. It is widely used for landscaping, moisture retention, weed suppression, and soil conditioning. Mulch is lightweight, fibrous, and highly variable in particle size and moisture content. These characteristics can create challenges with material flow, bridging, and dust generation. KWS designs conveying systems specifically engineered to handle fibrous organic materials while minimizing plugging, degradation, and maintenance.

- Biomass fuel and renewable energy applications
- Agricultural and environmental projects
Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Wood Chips, Shredded Bark, Ground Mulch, Dyed Mulch, Organic Blends |
| Bulk Density | 10-35 lb/ft³ (depends on moisture content and particle size) |
| Flow Behavior | Poorly flowing; fibrous particles tend to interlock and bridge |
| Abrasiveness | Low to Moderate Contaminants such as sand and grit may increase wear |
| Corrosiveness | Not Corrosive May retain moisture and promote biological activity |
| Dust Potential | Moderate Dry mulch can generate combustible dust and fines |
Handling Challenges
- Bridging and ratholing in hoppers and storage bins
- Variable moisture content affecting flow characteristics
- Fiber interlocking and plugging in conventional conveyors
- Dust generation and housekeeping requirements
- Material degradation from excessive mechanical handling
Summary
Mulch requires conveying and storage systems designed for lightweight, fibrous, and moisture-variable organic 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 biomass, wood products, and organic bulk materials, KWS ensures efficient, dependable, and low-maintenance operation for mulch handling systems.
