In the process of titanium dioxide screening, common titanium dioxide is 40-325 mesh or finer. The selection of vibrating screens should include many factors, such as particle size structure, specific gravity, water content, viscosity, temperature, processing capacity, etc. Usually, titanium dioxide is screened using rotary vibrating screens (with low production and high accuracy) or linear screens (with high production and lower accuracy than rotary vibrating screens). The three-dimensional vibrating screen and the ultrasonic vibrating screen can achieve a certain particle size distribution in the process of fine selection, making the particle size average and fine. In the rubber industry, titanium dioxide is not only used as a colorant, but also has the functions of strengthening, anti-aging and filling. Titanium dioxide is used in white and colored rubber products. Under sunlight, it has properties such as resistance to sunlight, cracking, discoloration, high elongation, and acid and alkali. Titanium dioxide for rubber is mainly used in automotive tires, rubber shoes, rubber flooring, gloves, sports equipment, etc.
