Titanium Dioxide Rotary Kiln
2025-08-30
1. Working Principle
Titanium dioxide, a scientifically named compound, is an important white pigment widely used in coatings, plastics, papermaking, inks, and other fields. In the production process, sintering is a key step that determines the quality and performance of titanium dioxide. The most suitable temperature range is 1450℃ ~ 1550℃ Within this temperature range, the particle size and shape of titanium dioxide can be optimally controlled, resulting in excellent performance in applications. If the temperature is too high, it will cause the particles to become too large, affecting the quality of titanium dioxide; if the temperature is too low, it will affect the color and quality of titanium dioxide.
The titanate slurry or particles treated by salting are added at the kiln tail. Due to the rotary kiln's inclination and slow rotation, the material moves in a circular motion inside the kiln, continuously tumbling while moving toward the kiln head. Fuel is burned in the furnace through the rotary kiln burner at the kiln head. During the material's movement toward the kiln head, it exchanges heat with hot air, completing drying, desulfurization, crystal transformation, and particle growth processes, and is calcined into titanium dioxide, which is discharged from the kiln head. The raw materials are mostly rutile pigment titanium dioxide, anatase pigment titanium dioxide, ilmenite, high-titanium slag, and acid-soluble titanium slag.
