Catalyst
Process Catalyst · Spent Catalyst · Catalyst Pellets · Beads · Extrudates
Catalysts are engineered materials used to accelerate chemical reactions in industrial processes. They are typically produced as pellets, beads, or extrudates composed of metal oxides, alumina, zeolites, or precious metals. Catalysts can vary widely in density, size, and strength, and may be friable or dusty. Spent catalysts may also be contaminated or hazardous, requiring contained handling systems. KWS designs conveying and feeding equipment that ensures controlled, dust-free transfer while minimizing material degradation.

Handling Challenges
- Dust generation and potential health hazards
- Pellet or bead breakage from mechanical conveying
- Bridging or ratholing in bins with irregular particle sizes
- Corrosion or contamination from spent catalysts
- Need for enclosed systems to prevent emissions or exposure
Summary
Catalysts require conveying systems designed for gentle handling, dust control, and containment. KWS Manufacturing provides engineered solutions—including screw conveyors, drag conveyors, and feeders—that ensure controlled, clean, and reliable material movement.
With proven experience in chemical and refining industries, KWS ensures efficient, safe, and low-maintenance performance for both fresh and spent catalyst handling systems.
