Manganese-Flakes

With this first trial, we wanted to make sure, that the metal sample will not ignite during or after grinding. We only took a smaller quantity of sample and reduced the main disk speed to 250 rpm.

After only 2 minutes of grinding, majority of sample use to be < 200 µm as desired; only a few particles use to show a maximum length of up to 300 µm.

To be on the save side, we recommend using a gassing lid and argon gas to prevent reaction with air (oxigen) – see result 2.

The desired amount has been given into a 500 ml grinding bowl which has been flouted with argon gas to remove oxygen.

After 3 minutes of grinding, the majority of sample has been ground to < 100 µm. A few particles use to have a length up to 200 µm. The desired task of grinding to < 200 µm has been achieved.
