Process for preparing aluminium trihydroxide |
摘要 |
The invention relates to a process for the milling-drying of a raw mixture containing aluminum trihydroxide having an average particle size D50 in the range from 50 to 130 μm and a specific BET surface area in the range from 0.01 to 0.5 m2/g and containing from 0.1 to 20% by weight of water, based on the raw mixture, which including the steps
i) introduction of the raw mixture into a milling-drying apparatus,ii) introduction of a hot air stream having a temperature in the range from 20 to 100° C. into the milling-drying apparatus so as to flow through the milling-drying apparatus andiii) comminution of the aluminum trihydroxide present in the raw mixture in the milling-drying apparatus. |

1. A process for the milling-drying of a raw mixture containing aluminum trihydroxide having an average particle size D50 in the range from 50 to 130 μm and a specific BET surface area in the range from 0.01 to 0.5 m2/g and containing from 0.1 to 20% by weight of water, based on the raw mixture, which comprises the steps
i) introduction of the raw mixture into a milling-drying apparatus, ii) introduction of a hot air stream having a temperature in the range from 20 to 150° C. into the milling-drying apparatus so as to flow through the milling-drying apparatus and iii) comminution of the aluminum trihydroxide present in the raw mixture in the milling-drying apparatus. |
