DATE SEED POWDER

*1: A grinding with sintered corundum is possible. While grinding, a lot of abrasion of Al2O3 has been formed (~ 1-3g). Especially because less possible abrasion is required, a usage of sintered corundum is not recommended.

*2: See the particles size distribution after 30 minutes of grinding with our ANALYSETTE 22 NanoTec on meas.no. 27103 on separate page (d10 <1,8µm; d50 <10,4µm; d90 <36.3µm).

*1: Because a direct grinding of sample is impossible, the sample has been pre grinded with PULVERISETTE 14 (see trial 3).

*2: 80ml of isopropyl alcohol (IPA) have been used for grinding the sample.

*3: For grinding the desired amount of sample (50g), a bigger bowl like the used 250ml bowl needs to be used. Therefore, we grinded the sample with maximum speed (650rpm) with our PULVERISETTE 6. While grinding, it has shown, that the grinding success is limited. We aborted grinding after 60mintes with a fineness of d10 <3µm; d50 <11µm ; d90<26µm (meas.no. 28663 with ANALYSETTE 22 NanoTec)). A longer grinding is still possible.
