BENEFITS

1. Hollow Structure + Spray-Drying = No Clumping & Fast Dissolution

  • The spray-drying process creates a porous hollow interior – when in contact with water, moisture penetrates the granule from all sides, dissolving it completely in 10-15 seconds.
  • No more lumps from powder “floating on water” or slow dissolution from dense flakes.

2. Dust-Free & Easy to Handle

  • 0.5mm micro granules eliminate the dust pollution of powder during production and application, protecting workers’ health and reducing material waste.
  • It’s also free-flowing, making it easy to blend with other fertilizers in automated production lines.
3. Versatile for Multiple Scenarios
  • High-efficiency liquid fertilizer production: Saves stirring time, shortens batch production cycles by 40%.
  • Mechanized fertilization: Compatible with precision seeding/fertilizing equipment, ideal for large-scale farms.
