Embodiment 1
[0039] Start the roller press mill, send the primary product of calcined titanium dioxide into the roller press mill, the feed rate of the roller press mill is 4.5t / h, and the distance between the rollers of the roller press mill is 0.6mm. Standard sieve, the sieve residue control range is 10%. The material on the sieve is returned to the roller press mill for re-grinding, the material under the sieve is beaten and dispersed by a high-speed dispersion system, and 3.0‰ monoisopropanolamine and desalted water are added for beating and dispersion, so that the slurry concentration is 650g / L. The dispersed slurry is pumped into a sand mill for sand grinding to obtain a titanium dioxide slurry. After sanding, the viscosity was measured by Brookfield rotational viscometer to be 120cP, and the particle size D50 of the slurry was measured by Malvern 2000 laser particle size analyzer to be 0.38μm.
Embodiment 2
[0045]Start the roller press mill, send the primary product of calcined titanium dioxide into the roller press mill, the feed rate of the roller press mill is 5.0t / h, and the distance between the rollers of the roller press mill is 0.9mm, after the first product is ground by the roller press mill, it passes through a 60-mesh Standard sieve, the sieve residue control range is 15%. The material on the sieve is returned to the roller press mill for regrinding, the material under the sieve is beaten and dispersed by a high-speed dispersion system, and 2.7‰ sodium silicate and desalted water are added for beating and dispersion, so that the slurry concentration is 620g / L. The dispersed slurry is pumped into a sand mill for sand grinding to obtain a titanium dioxide slurry. After sanding, the viscosity was measured to be 68cP by Brookfield rotational viscometer, and the particle size D50 of the slurry was measured to be 0.35μm by Malvern 2000 laser particle size analyzer.
