Prilling Machine

Forming technology for processing plants.

Over the years, we have built up an impressive track record in manufacturing prilling machines.

The first fertilizer prilling machine we built in the 1960s is still in operation today and continues to deliver a positive cash flow for our client. The proof of this track record is our ever-growing prilling reference list.

Types of prilling machines

Kreber Prilling Machines are characterized by high reliability, low operational expenses, and ease of operation.

Depending on the type of product, the required quantity, and the prilling tower conditions, we offer one of two types of prilling machines: the Kreber Static Prilling System or the Kreber Rotary Prilling System.

Prills sample

Prills for bulk properties offer 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 starage in silo installations
  • Precise dosage
  • No additives needed; pure materials

About prills and prilling

Prill Formation Possibilities

Explore which method of prilling meets your requirements.

Static Prilling

We offer the Kreber Static Prilling System for the conventional method of prilling. This type of system can contain one or more prilling heads and is very suitable for capacities ranging from 5 to 500 metric tons/day.

Rotary Prilling

The Kreber Rotary Prilling System has two rotary prilling buckets. This allows for quick changeover of prilling buckets, thus ensuring continuity of production. This type of system is suitable for capacities ranging from 75 to 5000 metric tons/day and comes in a number of standard models to which various applications can be flexibly added.

Vibro Prilling

Thanks to our innovative facilities, the R&D team is able to take prilling technology and customer solutions to the next level. One of our major developments is ‘vibro prilling’. Applying vibration to the melt results in more uniform prills with a narrowly defined prill size distribution. This principle can be applied to both static prilling and rotary prilling.


Microprilling (also sometimes referred to as spray cooling, spray congealing or spray chilling) is a technique that uses an atomizer to create a cloud of fine droplets. The resulting particles from this cloud are very small (D50<0.5mm). Due to their perfectly spherical shape these particles still earn their right to be classified as prills, rather than just a powder.
