Titanium dioxide screening machine

When screening titanium dioxide, titanium dioxide has the characteristics of ultra-fine, light, easy to dust and easy to agglomerate. Ordinary screening equipment is difficult to meet its screening accuracy and efficiency requirements. Therefore, screening equipment dedicated to titanium dioxide usually adopts structural forms such as rotary vibrating screen (circular vibrating screen), ultrasonic vibrating screen or airflow screen. Titanium dioxide can be screened in the range of 100-800 mesh during the screening process, with a processing capacity of 0.5-5 tons/hour. The 304 stainless steel closed structure is equipped with an ultrasonic net cleaning system, which can effectively solve the problem of electrostatic agglomeration of titanium dioxide, and the classification accuracy reaches ±3μm.

Titanium dioxide screening machine type selection

Standard Vibro Sifter is suitable for the classification of coarse or medium-sized titanium dioxide (such as 60~200 mesh), and realizes rapid screening by combining horizontal 360° rotation with vertical vibration. Suitable for primary screening, removal of agglomerates and large particle impurities.

Ultrasonic Vibrating Sieve is used for screening ultrafine titanium dioxide (such as 200 mesh, 500 mesh, and even up to 600 mesh). After being equipped with an ultrasonic system, high-frequency micro-vibration (3640kHz) is superimposed on conventional vibration, which can effectively prevent powder agglomeration and mesh blocking, and greatly improve the screening rate.

The airflow screen is suitable for TiO2 powders that are viscous, highly electrostatic, or slightly agglomerated. The airflow carries the material in the screen drum to complete the screening, which is suitable for ultrafine screening requirements with a mesh range of 200~800 mesh.

How to choose the mesh number of titanium dioxide screening machine?

Titanium dioxide screening machine is designed for efficient grading of fine TiO₂ powder. Common mesh sizes range from 100 to 500 mesh, ensuring precise particle separation. Equipped with ultrasonic systems, it prevents mesh clogging and improves throughput. Typical processing capacity ranges from 100 to 1000 kg/h, depending on mesh size and machine model.

Primary screening (coarse classification): 60 mesh, 80 mesh, 100 mesh, to remove lumps and impurities;

Intermediate classification (finished product particle size control): 120 mesh, 150 mesh, 200 mesh, to control the particle size range;

Precision screening (high-end products): 300 mesh, 400 mesh, 500 mesh and above, for cosmetic grade, food grade, pharmaceutical grade titanium dioxide.

The combination of multiple layers of sieves (such as three or four layers) can achieve precise grading of 2-4 particle sizes, making the product particle size control more refined and meeting the strict standards of particle size distribution in different application fields.

It adopts 304 stainless steel closed structure, with screening range of 100-800 mesh and processing capacity of 0.5-5 tons/hour. The screening efficiency of the whole machine can reach 85%~95%, especially in ultrasonic screening mode, which effectively destroys the electrostatic agglomeration of titanium dioxide through high-frequency resonance, so that the passing rate of fine powder below 325 mesh is increased by more than 30%. Equipped with intelligent control system, it can adjust the amplitude (0.5-3mm) and ultrasonic power (50-100W) in real time to ensure the classification accuracy of ±3μm. It is suitable for impurity removal of coatings, plastic-grade titanium dioxide and fine screening of food grade (E171). The explosion-proof design meets the requirements of GMP workshops.
