MINERALS & MATERIALS | RARE EARTHS
Dry milling and classification for rare earths.
Since the 1950s, rare earths have gradually become indispensable to high-tech industry. They are used in many fields: electric vehicles, wind turbines, computers or even in armaments such as missiles.
Depending on the product, the desired fineness and particle size distribution, the POITTEMILL Group offers different products and services. For rare earths, the choice is generally for the pendulum mill, which is ideal for high throughput and low energy requirements. The impact mill and hammer mill also offer many advantages for these applications.
The POITTEMILL Group offers a wide range of techniques for all stages of rare earth processing from pre-crushing to ultra-fine grinding and high-performance classification to meet the standards of today’s and tomorrow’s industries.
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.
