FLEX-MAT for the Fertilizer Industry

FLEX-MAT is engineered for the unique demands of fertilizer manufacturing and processing — where sticky granular materials like phosphate, potash, urea and NPK compounds create severe blinding conditions on conventional wire screens. Major high-vibration wire screen technology keeps screen openings clear by vibrating each wire at its own frequency, delivering consistent particle sizing and higher throughput in phosphate, potash and complex fertilizer production plants worldwide.

How FLEX-MAT Handles Sticky Fertilizer Materials

Fertilizer materials — particularly phosphate rock, potash and nitrogen-based granules — are among the most challenging materials to screen. High moisture content during processing, chemical coatings and hygroscopic properties cause conventional wire screens to blind rapidly, reducing sizing accuracy and forcing frequent shutdowns for cleaning and screen replacement.

FLEX-MAT independent wire vibration technology addresses the specific challenges of fertilizer screening directly — preventing buildup of sticky granular material on screen surfaces and maintaining consistent open area throughout the screening cycle, even on corrosive and chemically aggressive materials.

Documented results from fertilizer operations using FLEX-MAT include:

  • Compatible with all major vibrating screen brands in fertilizer plant configurations
  • Up to 4× longer screen media service life versus standard woven wire on phosphate
  • Elimination of blinding on sticky NPK, urea and DAP granules
  • Consistent on-spec product sizing — meeting agronomic grade requirements
  • Reduced downtime and lower screen maintenance cost per ton produced
