Raw ore is pulped by adding water and dispersant according to the set concentration requirements in a blender or pulper. The purpose of pulping is to disperse and separate kaolin from sandy minerals and plant impurities in order to prepare a slurry of suitable concentration for the next PTMS magnetic separator process. The impurities such as quartz, feldspar and mica in kaolin ore have coarse grain size, generally larger than 325 mesh, while kaolin has fine grain size, mainly concentrated in -2μm.

PTMS magnetic separator

 
Most quartz and feldspar coarse sand can be removed by spiral PTMS magnetic separator. Hydrocyclone series separation is adopted to remove kaolin fine sand (fine-grained quartz, feldspar and other impurities). Hydrocyclones with different diameters such as Ø75, Ø50 and Ø25 are generally adopted for multiple separation. Horizontal spiral series classification, according to different materials to adjust the process parameters (such as separation factor), to maintain the stability of product quality.

what is magnetic separation?

 
At present, hydrocyclone PTMS magnetic separator is also used for separation of kaolin in domestic beneficiation. However, due to the influence of flow and pressure changes, the product quality is difficult to stabilize at -2μm accounting for more than 90%, and the classification efficiency is not as good as that of horizontal spiral centrifugal series.
