Silica
SiO₂ · Silica Sand · Quartz · Crystalline Silica · Fused Silica · Silica Flour
Silica is a hard, crystalline mineral composed primarily of silicon dioxide. It occurs naturally as quartz and is processed into sand, flour, or fused forms depending on the application. Silica is dense, highly abrasive, and capable of generating fine dust that presents respiratory and explosion hazards. KWS designs conveying systems that handle silica safely and efficiently with abrasion-resistant components and dust-tight construction.

Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Crystalline Granules, Fine Powder, Fused Silica |
| Bulk Density | 80–120 lb/ft³ (depends on form and moisture) |
| Flow Behavior | Free-flowing but may compact when humid |
| Abrasiveness | Very High causes extreme wear on contact surfaces |
| Corrosiveness | Not Corrosive |
| Dust Potential | Very High fine silica dust is hazardous and requires strict containment |
Handling Challenges
- Severe abrasion and wear on screws, housings, and liners
- Fine dust generation posing serious health and explosion hazards
- Material compaction and bridging when exposed to moisture
- Build-up and plugging at transition points
- Environmental and regulatory compliance for silica dust emissions
Summary
Silica requires conveying and storage systems designed for extremely abrasive, dense, and dusty materials. KWS Manufacturing provides engineered solutions—including screw conveyors, belt conveyors, and drag conveyors—constructed with hardened materials and enclosed housings to ensure long-lasting performance and worker safety.
With extensive experience handling abrasive minerals and industrial powders, KWS ensures efficient, durable, and compliant operation for silica handling systems.
