Fine powder classification
WebMay 1, 2024 · On the contrary, in the case of fine powders (Geldart’s classification C powders), the interparticle forces are considerable and much larger in magnitude than the gravitational forces. Therefore, the above-mentioned equilibrium cannot be reached, since the cohesive forces acting among particles prevent the achievement of a free-floating state. WebT-Sepax high-efficiency three-separation powder classifier divides the material into three parts, namely coarse powder, medium coarse powder and fine powder. The primary classification area pre-separates the coarse particles in the mixed powder and collects them in the coarse powder cone; the second classification area, the third is the precise ...
