Copper Sulfate
CuSO₄·5H₂O · Blue Vitriol · Cupric Sulfate · Roman Vitriol · Blue Stone
Copper sulfate is an inorganic salt that appears as blue crystalline granules or powder in its pentahydrate form. It is soluble in water and slightly acidic, with strong hygroscopic and corrosive tendencies when exposed to moisture. The material is dense, free-flowing when dry, but can cake and clump under humid conditions. KWS designs conveying systems constructed from corrosion-resistant materials to ensure safe, consistent, and low-maintenance handling of copper sulfate.

Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Crystalline Granules or Fine Powder (Pentahydrate or Anhydrous) |
| Bulk Density | 75–95 lb/ft³ (varies with moisture and crystal size) |
| Flow Behavior | Free-flowing when dry; cohesive when exposed to humidity |
| Abrasiveness | Low to Moderate may cause mild wear on metal surfaces |
| Corrosiveness | High corrosive to carbon steel in moist environments |
| Dust Potential | Moderate fine particles require containment and ventilation |
Handling Challenges
- Caking and clumping due to moisture absorption
- Corrosion of carbon steel equipment and fasteners
- Dust generation requiring enclosure and collection
- Worker exposure concerns from skin and respiratory irritation
- Segregation of granule sizes during conveying and storage
Summary
Copper sulfate requires conveying and storage systems designed for corrosive, hygroscopic materials. KWS Manufacturing provides engineered conveying solutions—including screw conveyors, drag conveyors, and feeders—constructed from stainless steel or polymer-lined materials to resist corrosion and maintain consistent flow.
With extensive experience handling chemical salts and hygroscopic powders, KWS ensures efficient, safe, and long-lasting performance for copper sulfate conveying systems.
