I need some suggestions and suitable ball mill for mixing the elemental powders of 325 mesh size like titanium, tungsten,carbon,aluminium powders etc..
Powders widely dissimilar, particularly in terms of particle size and density, of poor flowability, or cohesive, are often mixed in planetary or drum-type ball mills, often with some added processing agent to improve homogenization. This kind of mixing alters the size distribution of the powders, as they are also milled while being mixed, and may imply subsequent drying of the powder mixture ― which may turn into a paste. Safety concerns, as those posed by many metal powders, are also to be considered while selecting a particular mixer type and mixing operating conditions. Purity concerns (due to possible powder contamination) and hardness must be considered while selecting the materials that contact with the powders.
About powder dry mixing ― Shaker-type powder dry mixers are often preferred for smaller scale application (e.g. laboratory scale). For larger scale or for scale-up tests, the V-shaped tumble blender may be preferred. About this last blender, you may want to check:
