Calcium Carbonate Prills
Calcium Carbonate (CaCO3) · Limestone Prills · Calcium Carbonate Pellets · Pelletized Lime · Prilled CaCO3
Calcium carbonate prills are pelletized or granulated particles made from finely ground calcium carbonate. The prilled form improves flowability, reduces dust generation, and allows more accurate feeding compared to fine powder. While generally free-flowing and easy to handle when dry, calcium carbonate prills can break down into fines during conveying, creating dust and potential buildup. KWS designs conveying systems that provide gentle, consistent handling while minimizing degradation, dust, and equipment wear.

Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Prills, Pellets, Granules, Coated Agglomerates |
| Bulk Density | 55-80 lb/ft3 (depends on prill size, porosity, and moisture) |
| Flow Behavior | Generally free-flowing; may bridge or compact if fines or moisture are present |
| Abrasiveness | Moderate Mineral particles can cause gradual wear on equipment surfaces |
| Corrosiveness | Not Corrosive Moisture can promote mild surface rusting |
| Dust Potential | Moderate Prills reduce dust, but fines may form during handling |
Handling Challenges
- Prill degradation and fines generation during mechanical conveying
- Dust buildup at transfer points and discharge areas
- Bridging or ratholing when fines accumulate in bins or hoppers
- Abrasive wear on screws, troughs, and liners over time
- Moisture exposure causing clumping or inconsistent feed rates
Summary
Calcium carbonate prills require conveying and storage systems designed for free-flowing, moderately abrasive, and degradation-sensitive materials. KWS Manufacturing provides engineered conveying solutions-including screw conveyors, drag conveyors, and feeders-that ensure consistent flow, minimize dust, and protect prill integrity.
With extensive experience handling calcium carbonate, limestone, and mineral additives, KWS ensures efficient, reliable, and low-maintenance operation for calcium carbonate prill handling systems.
