Key Technologies

Innovative Solutions for High-Performance Processing

  • Granulation and Prilling
    We provide advanced systems to convert molten or dissolved materials into solid, uniform particles. These solutions ensure optimal handling, mechanical strength, and performance in field applications.
    Applications: NPK, ammonium nitrate, urea, sulfur-coated urea, methylene urea.
  • Fattening and Pure Ammonium Nitrate Granulation
    Our fattening technology improves granule size and hardness through controlled agglomeration. We also offer dedicated systems for pure AN granulation for both agricultural and industrial-grade applications.
    Applications: Fertilizer-grade and industrial-grade ammonium nitrate.

  • Bi-Fluid Granulation
    A hybrid approach that combines fluid bed and rotary drum technologies, ideal for specialty fertilizers. It enables precise control over particle size, strength, and coating quality.
    Applications: Methylene urea, sulfur-coated urea, calcium nitrate.
  • Gas Treatment and Filtration
    Tailored for phosphoric acid plants, our systems—including MECS Dynawave scrubbers and mist eliminators—ensure effective removal of pollutants from process gases, supporting strict environmental standards.
    Applications: Phosphoric acid production, phosphogypsum handling.
  • Phosphogypsum Processing
    Ballestra’s solutions ensure safe and sustainable management of phosphogypsum, a by-product of phosphoric acid production. Our technologies support waste reduction, reuse strategies, and environmental protection.

Integrated Solutions Across the Production Cycle

Ballestra’s comprehensive portfolio of process unit operations ensures that fertilizer and inorganic chemical producers benefit from cutting-edge technologies that enhance efficiency, optimize product quality, and minimize environmental impact. From granulation to gas treatment, Ballestra offers integrated solutions for the entire fertilizer and chemical production cycle.
