Dry milling and classification for the nuclear industry.

The POITTEMILL Group has developed a complete range of patented industrial processes to meet your requirements for the treatment of your products for the nuclear, defence or aerospace industries. The POITTEMILL Group offers a wide range of industrial processes for fine grinding, particle size reduction, separation, and application classification to provide the most suitable engineering solutions for full operational compliance.

As an expert manufacturer of high-quality engineering, we bring our know-how in processing a wide variety of applications such as ceramic matrix composites (CMC), oxidisers, technical products, nitrocellulose, potassium permanganate.
In order to comply with the strict safety regulations of these sectors (in particular the ATEX standards), the POITTEMILL Group has developed confined systems that allow easy and accessible cleaning and dismantling in all types of conditions.

Equipped with the latest high-quality industrial engineering technologies, the POITTEMILL Group guarantees a service that takes into account the constraints of your projects over the long term.


Sustainable processing solutions

Fully integrated solutions are the key to providing optimised processes that help you both reduce costs and make more sustainable use of valuable resources.

These systems are based on the principle of:
• Reliability and safety
• Low operating and maintenance costs
• Guaranteed hygienic, customer-oriented process solutions
• Easy cleaning
• Energy saving

The diverse characteristics of powders in these types of industries require a combination of engineering skills and experience to design quality systems to meet the expectations of today’s and tomorrow’s customers.


Process testing and development

The POITTEMILL Group has its own scientific laboratory as well as a test center which is unique in France. It is in this test center that the dialogue between customers and the technical teams begins, but it is also here that detailed analyses of their raw materials are carried out to obtain complete information on the execution of the task set.

Our development and engineering team is always available to help you explore new and innovative processes and applications.

Our testing facilities offer exceptional opportunities to test ingredients, machines, parameters, and processes, whether in the laboratory, pilot or industrial scale, to ensure you achieve the necessary product quality and operating efficiency.
