Understanding Lime Storage Challenges

Lime, especially hydrated lime, is abrasive and chemically active, requiring storage solutions that prevent contamination, minimize dust leakage, and avoid flow issues such as blockages or bridging.

Challenges in lime silo design include:

• Corrosion and Erosion Resistance: Lime, particularly in powdered or slurry form, is abrasive and can degrade unprotected storage vessels.
• Dust Containment: Lime dust can be a health hazard and environmental pollutant, thus airtight design and dust collection systems are critical.
• Flowability: Maintaining consistent and reliable discharge without bridging or rat-holing in the silo.
• Structural Strength: To hold large volumes of dense material safely.
• Easy Inspection and Maintenance: Access for regular inspection and cleaning without disrupting operations.
• Safe Integration: Features to facilitate loading, unloading, sealing, and pressure control

What Are Glass-Fused-to-Steel (GFS) Lime Silos?

Center Enamel’s GFS lime silos utilize a proprietary process where molten glass coating is fused to steel plates at temperatures between 820°C and 930°C. This process results in a strong chemical and physical bond, providing a smooth, abrasion-resistant, and corrosion-proof surface on the interior and exterior of the silo.

Benefits of GFS for lime silos include:

• Superior Corrosion and Wear Resistance: Glass coating protects steel from abrasion and lime’s alkalinity.
• Smooth Surface: Minimizes lime buildup and enhances flowability.
• Modular Bolted Panel Construction: Enables rapid and flexible onsite assembly with leak-proof, airtight joints.
• Long Service Life: GFS silos can last 30+ years with minimal maintenance.
• Custom Design: Cylindrical silos with optimized cone angles to prevent bridging.
• Environmental Protection: Airtight seals prevent dust escape and environmental contamination.
