RECYCLING & RECOVERY
Processing by dry grinding and classification for electronic cards
POITTEMILL has a new patented technology that allows the separation of metals and polymers contained in obsolete electronic cards, and thus treats a large part of the urban mines of electrical and electronic waste.
Inherited from mining techniques, mechanical separation is the subject of much research. By grinding the material more finely (less than 100 µ) so as to free the metals from the epoxy resin, the metal content is improved (which then reaches 90%).
The treatment of light residues is an important environmental issue.

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.
