The invention relates to a process for the mill-drying of a crude mixture comprising aluminium trihydroxide with an average particle size D50 in the range from 50 to 130 μm and a BET specific surface area in the range from 0.01 to 0.5 m2/g and 0.1% to 20% by weight of water, based on the crude mixture, comprising the steps of i) feeding the crude mixture into a mill-drying assembly, ii) feeding a stream of hot air at a temperature in the range from 20 to 100°C into the mill-drying assembly, to flow through the mill-drying assembly, and iii) comminuting the aluminium trihydroxide present in the crude mixture in the mill-drying assembly. |
