Anticaking
Managing particle interaction to stabilize material handling
The role of anticaking in mining operations
Anticaking is a post‑treatment stage focused on preventing the formation of lumps or agglomerates in powdered or granulated mining materials during storage, transport, and handling. Many mined and processed materials are hygroscopic, meaning they absorb moisture from the surrounding environment and are prone to caking under pressure, humidity, or temperature variation.
This functional area is responsible for preserving flowability and material consistency from production through logistics and end use. Effective anticaking ensures that materials can be conveyed, metered, blended, and applied without blockages, interruptions, or reprocessing.
Anticaking challenges are intensifying as mining operations handle finer particles, higher throughput volumes, longer storage durations, and more variable environmental conditions. Increased moisture exposure and tighter logistics tolerances make flow reliability a critical operational requirement rather than a downstream convenience.
Function‑led control of moisture and particle interaction
Anticaking performance depends on how particles interact with moisture and with each other at their surfaces. Nouryon’s anticaking solutions focus on surface‑active chemistry that modifies particle surfaces to prevent moisture‑driven adhesion and mechanical bonding.
Through the formation of hydrophobic surface layers and physical barriers between particles, anticaking chemistry enables:
• Reduced moisture adsorption on hygroscopic materials
• Lower interparticle friction and adhesion
• Improved lubrication of granules to reduce abrasion and dusting
• Preservation of free flowing behavior under storage and
handling stress
These chemistry functions are delivered through controlled surface coating of particles, ensuring that anticaking performance is maintained without altering the bulk properties of the material.
