PREPARATION OF DIFFERENT KAOLIN SLURRY WITH HIGH SOLID CONTENT

Two types of kaolin slurry with high solid content were prepared,and effects of the dosage of dispersant and pH on the solid content to kaolin slurry were investigated.The results show that the kaolin slurry with high solid content can be prepared by anion or cation dispersant,the anion type system is alkaline while the cation type system is acidic.The optimum added amounts of dispersant need to be determined when the slurry is to be prepared.
