*1: During grinding time of 10 min the outside of the grinding bowl reaches >70°C. Before loosing the bracing, we recommend a cooling time of 60min to eliminate retardation of boiling. (in case of high internal pressure the bracing always should be opened with caution). |

Because of fines (bigger surface) , we had to put another 140ml water in the bowl, after 10min grinding. Before loosing the bracing, the temperature should be < 60°C. |

*1: After a grinding time of 20min the sample volume is such grown, so that the grinding bowl was totally filled up. The suspension was creamy. We extracted 130g of the current sample and diluted the leftover with 100ml water. Therefore it is advisable to shift 40g of the mixed salt with 350ml water. Thereby the grinding time could be reduced and the endfineness is gonna be finer. Because of the temperature development during grinding we recommend a 5min grinding circle followed by a 20min cooling phase. Before opening the grinding bowl the temperature should be < 60°C. |
