Sand
SiO₂ · Silica Sand · Construction Sand · Foundry Sand · Frac Sand · Industrial Sand
Sand is a granular material composed primarily of quartz (silicon dioxide) and other mineral particles. It is heavy, abrasive, and free-flowing, though high moisture or fine particle content can cause clumping or bridging. In industrial environments, silica dust can pose respiratory and explosion hazards. KWS designs conveying systems for sand that are rugged, wear-resistant, and enclosed for dust control and operator safety.

- Oil and gas hydraulic fracturing (frac sand)
- Filtration and water treatment media
Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Dry Sand, Damp Sand, Fine Silica, Coarse Granular Sand |
| Bulk Density | 85–120 lb/ft³ (depends on moisture and grain size) |
| Flow Behavior | Free-flowing when dry; cohesive and compactable when wet |
| Abrasiveness | Very High causes severe wear on metal surfaces |
| Corrosiveness | Not Corrosive but may retain moisture that promotes rusting |
| Dust Potential | High fine silica particles are hazardous and require dust control |
Handling Challenges
- Severe wear and abrasion on conveying components
- Dust generation and potential for airborne silica exposure
- Bridging and compaction in hoppers when moisture is present
- Material buildup at transition points and discharge chutes
- Noise and impact damage from heavy particle flow
Summary
Sand requires conveying systems designed for high abrasion resistance, dust containment, and consistent flow. KWS Manufacturing provides engineered conveying solutions—including screw conveyors, belt conveyors, and drag conveyors—constructed with wear-resistant materials to ensure reliable performance and long equipment life.
With decades of experience handling abrasive and dense minerals, KWS ensures safe, efficient, and low-maintenance operation for sand conveying systems.
