| abstract |
The invention relates to a method for producing a fine-particle, dust-like or powdery material, by grinding and/or deagglomerating a particulate material, especially a granular and/or agglomerated material and/or by mill drying a damp, preferably fine-particle material, especially a filter cake. The aim of the invention is to enable the comminution of a material or product having distinctive agglomeration and/or adhesion properties. To this end, the grinding and/or deagglomeration and/or mill drying is carried out in an air vortex mill (1), the stator sifter region (12) thereof being acted upon by additional air, especially compressed air, during the grinding and/or deagglomeration and/or mill drying. |
