Cement Clinker
3CaO·SiO₂ and 2CaO·SiO₂ · Clinker · Cement Nodules · Portland Clinker · Sintered Cement Material
Cement clinker is a hard, nodular material produced by sintering limestone and clay minerals at high temperatures in a rotary kiln. It is subsequently ground with gypsum and other additives to produce Portland cement. Clinker is dense, abrasive, and irregularly shaped, with particle sizes typically ranging from 1/8 inch to 2 inches. KWS designs heavy-duty conveying systems with wear-resistant materials to handle clinker efficiently while minimizing downtime and maintenance.

Common Names
Common Forms
Applications
- Feedstock for Portland cement grinding and finishing
- Raw material for blended and specialty cements
- Construction materials and structural additives
- Research and testing in cement quality control
Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Irregular Nodules, Granules |
| Bulk Density | 75–95 lb/ft³ (depends on size and temperature) |
| Flow Behavior | Free-flowing but may compact when hot |
| Abrasiveness | Very High causes severe wear on conveying surfaces |
| Corrosiveness | Not Corrosive Slightly alkaline and non-corrosive when dry |
| Dust Potential | Moderate fines produced during conveying and transfer |
Handling Challenges
- Severe abrasion from coarse, dense particles
- High temperature of freshly produced clinker causing thermal stress
- Dust generation during transfer and cooling stages
- Equipment wear and maintenance from impact and friction
- Bridging or plugging when material cools and compacts in hoppers
Summary
Cement clinker requires conveying systems designed for extreme abrasion, impact, and temperature conditions. KWS Manufacturing provides engineered heavy-duty solutions—including drag conveyors, screw conveyors, and bucket elevators—constructed from high-strength, heat-resistant materials for reliable performance.
With decades of experience handling clinker and other abrasive industrial minerals, KWS ensures efficient, durable, and low-maintenance conveying systems for cement production environments.
