New Planetary Ball Mills from Heriot-Watt University

As such, the milling has to be paused every 30 minutes to allow the sample/jars to cool down. If left to run continuously, the sample can reach temperatures up to 600 o C. Planetary ball mills offer the best performance when it comes to grinding materials but the aforementioned limitations have stopped many researchers from using these ball mills.
