Process Factors Using Centrifugal Spray Drying to Prepare Bauxite Microspheres

Abstract:

The centrifugal spray drying process of bauxite slurry was studied to investigate the influence of slurry solid content on the particle size distribution and the sphericity of the microspheres, and so was operation technology on average diameter and the sphericity of the microspheres. The optimal operation parameters are obtained to prepare high spherical microspheres bauxite with the diameter distribution of 100 μm and whose particle size distribution is narrow: the slurry solid content is 70 wt%, the dry air temperature is 250 °C, the rotation rate of spray head is 6000 rpm and the feed flow rate is 1 L/h in the experiments.
