*1: See our particle size analysis after 120min with ANALYSETTE 22 NanoTec, on Meas.No 7647.

*2: In the beginning of the grinding process, the bowls outside will become very hot. 65°C after the first minute, over 80°C after the second minute. Therefore, we programmed a grinding time of only 2minutes and a programmed pause for 20minutes. This procedure was also done to the following grinding trials.

*3: The samples volume rises to much. We abort the grinding and started a new trial with less sample (trial 2).

*1: We started with 25ml and added about 7-8ml each 30min.

*2: After 1 hour the volume of sample was to high. We took out about 8g of sample and replaced it with 8ml of benzine.

*3: See our partice size analysis after 120min with ANALYSETTE 22 NanoTec, on Meas.No 7548.

*1: We started with 25ml and added about 7-8ml each 30min.

*2: See our particle size analysis after 120min with ANALYSETTE 22 NanoTec, on Meas.No 7604. We changed the solvent to isopropylic alcohol and calculation model to frauenhofer calculation for the next trial (trial 4).

*1: We started with 25ml and added about 5-6ml each 30min.

*2: After the first 2 minutes, the grinding sets outside temperature was 96°C, therefore, we grinded for only 2 minutes and paused for additional 20minutes before we proceeded the grinding.

*2: See our particle size analysis after 120min with ANALYSETTE 22 NanoTec, on Meas.No 7722. Find as well the analysis after 60min with ANALYSETTE 22 NanoTec on Meas.No 7671 (d50 < 0,375).

There is no big difference in fineness after 1h and 2h of grinding. Therefore, a longer grinding as 1h is not recommended.
