[0013] Example: Add 800 kg of raw material dititanium trioxide and 3200 kg of secondary purified water into the stirring tank, prepare a solution with a concentration of 25%, stir for half an hour, adjust the pH value to 6.5 while stirring, and then pass through GSF high-efficiency The wet pulverizer is used for crushing, stirring, and re-crushing, and the crushing is repeated for 1.5 hours, and then pumped into the GSDF25J ultra-fine ultrafine machine for a fractional separation. The particle diameter of the titanium dioxide after the primary fractionation is 0.4 μm. Then it is pumped into the GSDF10 ultra-fine ultrafine machine for secondary fractionation and separation, and the particle diameter of titanium dioxide after the secondary fractionation treatment is 0.3 μm. After secondary fractionation and separation, the titanium dioxide raw material and dilute sulfuric acid solution are sent to the precipitation tank, 80 kg of ammonium bicarbonate precipitation agent is added,...
