Grinding Mechanochemistry

Colour changes during grinding can also be indicative of reaction success.Therefore, mechanochemistry can allow for rapid screening of a huge number of different reactions in the search for interesting materials.However, dont be too quick to dismiss an unsuccessful reaction if you havent tried liquid-assisted grinding lag.

We are a professional and innovative company with more than 60 years of experience in the field of crushing and mineral processing. Our new products always carry the latest technology to serve our customers.
