Advanced Solutions for Granulation

Prilling Tower and Prilling Plants

Ballestra specializes in the design and engineering of prilling towers and prilling plants, offering state-of-the-art solutions for the production of spherical granules and particles. The prilling process, also known as spray cooling, spray chilling, or melt-spray, is essential for industries seeking efficient and cost-effective methods for solidifying molten materials into granulated forms.

What is Prilling?
Prilling is a granulation process where molten products are atomized into small droplets and solidified by cooling in an inert gas or air medium. The resulting granules, also called prills, are characterized by their uniform shape and size, offering significant advantages for dosing, transportation, storage, and processing.

Key Features of the Prilling Process:

  • Atomization Methods: The molten liquid is atomized using pressure or bi-fluid nozzles, creating droplets of controlled size.
  • Particle Sizes: Particle diameters can range from a few microns to 2 mm. Larger granules require tower heights that may not be practical.
  • Tower Configuration: In modern prilling towers, the molten material is injected from the top, and droplets are solidified while descending through a cooling medium in a counterflow system.

Applications and Advantages of Prilling
Prilling is widely used in chemical and industrial processes to transform molten materials into granulated forms. This method enhances the handling and usability of products, offering advantages such as:

  • Improved dosing accuracy
  • Enhanced transportation and storage properties
  • Simplified processing in downstream applications
