About prilling

Prills and prilling are the smart choice for countless applications. Find out how your product and process can benefit from this solidification technology.

Prills: unique characteristics and advantages

Prills are grains of solid substances formed from molten drops. The result? A free flowing product with low dust and a narrow particle size distribution.

Prills are spherical and naturally resistant to abrasion or damage. Since no additives are necessary in the prilling process, prills of your product are 100% pure.

Thanks to their size and shape, prills have the smallest possible contact surface area and high bulk density. In bulk, prills behave like a fluid which is beneficial for transport, storage and further processing.

This is why prills offer the ideal form of solidification for a wide range of substances and markets.

Example prills

Prills for bulk properties offer you significant advantages:

  • Excellent 'free flowing' properties
  • Low tendency to stick and agglomerate
  • Distinguished for air lifting
  • Highly resistant to abrasion or damage
  • Minimal dust formation
  • Well suited for transportation in road tankers, containers and big bags
  • Excellently storable in silo installations
  • Precise dosage
  • No additives needed; pure materials

Prilling: more control,
more profit

Prilling is a extremely effective finishing technology and offers you the following advantages over other solidification methods:

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.

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

Our 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 prill tower and additional 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.
