A Mortar Grinder PULVERISETTE 2 is capable to grinding pure silicone to a d90 < 160 µm. As requested, we ground the sample 3 times with the desired grinding sets.
Machine has been set to 12,5 daN and 30 minutes. After the grinding time is finished, exactly 90 % of sample is able to pass a test sieve with 160 µm mesh. For a better fineness, longer grinding times are possible.
