· Dry process is a simple and economical processing technology. After the mined raw ore is crushed to 25.4mm by the hammer crusher, it is fed into the cage crusher to reduce the particle size to 6.35mm. The hot air in the cage crusher reduces the moisture of the kaolin from 20% to 10% or so. The crushed ore is further ground by an air-blown

· Overall, the viscosity of kaolin pulp showed a linearly decreasing trend after kneading. In general, a lower viscosity means better dispersing properties. The viscosity of K6 decreased by 65.41% (688 mPa·s vs. 238 mPa·s) compared to K0, indicating the beneficial role of kneading on dispersibility.
