Titanium dioxide centrifugal spray dryer

Overview of Titanium Dioxide

Titanium dioxide, white solid or powdered amphoteric oxide, molecular weight: 79.87, is a white inorganic pigment with non-toxicity, good opacity, whiteness and brightness, which is regarded as a white pigment with ideal performance at present. Titanium dioxide has strong adhesion, not easy to start chemical changes, and the color is snow white.

It can be used in coating, plastic, paper making, printing ink, chemical fiber, rubber, cosmetic and other industries. It has a high melting point and is also used to make refractory glass, glazes, enamel, terra cotta, and high-temperature resistant labware. Titanium dioxide is an important white pigment and porcelain glaze. It is used in paint, ink, plastic, rubber, paper, chemical fiber, watercolor pigment and other industries.

Titanium dioxide centrifugal spray dryer working principle

The air is filtered and heated, and enters into the air distributor at the top of the dryer, and the hot air enters into the drying chamber uniformly in spiral shape. The material liquid is sprayed into very fine mist liquid beads by the high-speed centrifugal atomizer at the top of the tower (rotating), which can be dried into finished products in a very short time by contacting with the hot air in parallel flow. The finished product is continuously output from the bottom of the drying tower and cyclone separator, and the exhaust gas is exhausted by the fan.

Note: The evaporation of water is related to the characteristics of the material and the hot air inlet and outlet temperatures. When the outlet temperature is ^90oC, the moisture evaporation curve is shown in the above figure (for selection reference), with the continuous updating of products, the relevant parameters change without prior notice.
