Prilling Nitrates

A far superior alternative to granulation.

Wealth of experience

One of the markets in which we have operated for decades is the fertilizer market. You can benefit from our knowledge and experience in this area when it comes to prilling ammonium nitrate.

Want to know more about the ammonium nitrate prilling process? Our prilling experts would be pleased to answer your questions about prilling ammonium nitrate or prilled ammonium nitrate.

For more information about the main principles of prilling, please read the following knowledge article: prilling meaning and prill definition.

Prilling is particularly well suited for the following nitrates and other substances:

  • Ammonium nitrate
  • Sodium nitrate
  • Potassium nitrate
  • Calcium nitrate
  • Magnesium nitrate
  • Mono-ammonium phosphate / mono-potassium phosphate
  • Potassium nitrate
  • Potassium sulphate

Prills sample

Prilled ammonium nitrate in bulk offers significant advantages:

  • Excellent 'free flowing' properties
  • Low tendency to stick and agglomerate
  • Distinguished for air lifting
  • Highly resistant to abrasion and damage
  • Minimal dust formation
  • Excellent for storage in silo installations
  • Precise dosage
  • No additives needed; pure materials

About prills and prilling

Prilling nitrates:
more control, more profit

Prilling ammonium nitrate offers the following advantages over other solidification methods such as granulation:

Prilling is one of the most economical finishing technologies in the world for large outputs. Compared with other solidification methods such as granulation and pastillation, CAPEX and OPEX will be multiple times lower at increased capacities.

Prilling makes it easy to scale up or down capacity in a range of 70-110% of the original design capacity. That makes it an extremely flexible part of your total production process. Quickly adapt to changes in the market? With prilling you can.

The high degree of ‘self-control’ makes prilling a robust finishing technology with a very stable processing procedure. It can therefore play a vital role in guaranteeing the continuity of your process and quality of your product.

The prilling process requires minimal energy consumption. In fact: it is the most energy-efficient solidification technology available. This helps you to minimize your operational expenses.

Prilling equipment is easy to operate. Due well defined process operating parameters and small number of equipment items. As a result you benefit from low operating and maintenance costs.

With the design of our prilling tower and additional prilling equipment, you benefit from a relatively small footprint compared to other solidification technologies.

Thanks to a constant stream of technical innovations, such as state-of-the-art air inlet filtration and scrubber technologies, prilling is now a much cleaner finishing technology than it ever has been.
