Calcium Carbonate
CaCO₃ · Limestone · Calcite · Aragonite
Calcium carbonate is one of the most widely used industrial minerals. While abundant and versatile, it presents challenges in conveying and handling due to its adhesive, cohesive, and sometimes fluidizing nature. KWS designs and manufactures robust equipment solutions to ensure consistent flow, reduced maintenance, and safe, dust-free operation.

Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Chalk, Limestone, Marble |
| Bulk Density | 35–60 lb/ft³ |
| Flow Behavior | Sluggish, adhesive, prone to packing and caking |
| Abrasiveness | Moderate Can cause wear on metal surfaces |
| Corrosiveness | Not Corrosive |
| Dust Potential | High Fine airborne particles require containment |
Handling Challenges
- Bridging and ratholing in hoppers
- Flood-feeding and inconsistent discharge rates
- Filter blinding and dust generation
- Product buildup inside conveyors
Summary
Calcium carbonate is a challenging bulk solid requiring equipment designed for controlled flow, abrasion resistance, and dust containment.
KWS Manufacturing provides engineered solutions including screw conveyors, drag conveyors, and screw feeders tailored to meet these challenges.
With decades of experience handling difficult materials, KWS ensures reliable performance, long equipment life, and reduced maintenance in calcium carbonate applications.
