Titanium dioxide (TiO₂) is the world’s most widely used white pigment, essential in industries such as coatings, paints, inks, plastics, paper, rubber, fibers, and ceramics. As global production and consumption of TiO₂ continue to expand, manufacturers face increasing challenges in achieving consistent particle size and purity while maintaining high throughput.
Due to its fine particle size, strong adhesion, and tendency to agglomerate, TiO₂ is notoriously difficult to screen using traditional vibrating sieves. Problems like mesh blinding, reduced efficiency, and inconsistent separation are common. To overcome these issues, Sanyuantang Machinery provides two industry-proven solutions — the Ultrasonic Vibrating Screen and the Horizontal Centrifugal Sifter — both designed to ensure clean, precise, and efficient TiO₂ powder classification.
The ultrasonic vibrating screen combines traditional rotary vibration with high-frequency ultrasonic technology. This system introduces ultrasonic energy to the screen mesh, effectively preventing mesh clogging and improving screening accuracy.
The ultrasonic generator transmits high-frequency vibrations through a transducer to the screen surface. These micro-vibrations disrupt particle adhesion and disperse agglomerated TiO₂, while the primary motor vibration ensures uniform material movement across the screen, achieving fine and consistent separation.
Clog-free operation & higher throughput: Prevents mesh blocking and boosts screening efficiency by up to 30%, ideal for fine separations from 2 to 635 mesh.
High precision & stable performance: Maintains sieving accuracy within ±5%, ensuring consistent product quality.
Easy cleaning & fast changeover: Reduces material residue on the mesh by more than 80%, simplifying cleaning between batches and enabling quick material changes.
For applications involving lightweight, fine, or low-density powders, the horizontal centrifugal sifter provides an ideal solution. Using centrifugal force combined with airflow motion, this system enables continuous, dust-free screening.
Material enters the screen chamber and is propelled by a rotating paddle, ensuring full contact with the mesh. Fine particles pass through the screen under airflow pressure, while larger particles are discharged. The entire process is fully enclosed, preventing contamination and powder loss.
Perfect for fine, sticky, or agglomerated powders: Specifically designed for materials like titanium dioxide that tend to clump or bridge.
Dust-free, safe, and environmentally friendly: Fully enclosed design eliminates powder leakage and meets industrial hygiene and environmental standards.
High capacity & continuous operation: Prevents powder buildup, delivering 20–40% higher throughput than conventional vibrating screens — ideal for large-scale TiO₂ production lines.
TiO₂ powders may contain trace acids or alkalis. To prevent corrosion and contamination, screens should be made of 304 or 316L stainless steel. For specific applications, nylon mesh may be used as an alternative.
Ensure that the titanium dioxide is completely dry before screening. Moisture causes clumping, severely affecting separation efficiency. A drying step before screening is highly recommended.
Premium-grade TiO₂ requires extremely low iron impurity levels (typically ≤50 ppm). Installing a magnetic separator before or after screening removes metal contaminants and ensures product purity.
For stable and efficient operation, screening systems should be integrated with screw feeders, hoppers, and automatic packing machines, forming a fully automated production line that minimizes manual handling.
