Titanium dioxide rotary kiln

Titanium Dioxide Rotary Kiln

Our titanium dioxide rotary kiln is a specialized industrial rotary kiln developed based on the domestic sulfuric acid process for titanium dioxide production. It features a suitable aspect ratio. High-temperature heating of metatitanic acid within the kiln allows for efficient drying, crystal transformation, and particle growth. It is suitable for calcining anatase-type and rutile-type titanium dioxide pigments. Common fuels include coal gas, natural gas, and diesel.

Daily Output: 30-67 tons/day

Models: Ø2.4×38m-Ø3.2×55m

Calcination Temperature: 860-920°C

Application: Suitable for calcining anatase-type and rutile-type titanium dioxide pigments in the sulfuric acid process for titanium dioxide production.

Titanium Dioxide Rotary Kiln Product Introduction

This series of rotary kilns features the same structure as conventional rotary kilns. The kiln body is constructed of welded steel plates, mounted at an angle and supported on a roller assembly. It is driven by a main motor, a reducer, and a large ring gear. The kiln interior is insulated with refractory materials. During operation, materials are loaded at the kiln's rear and unloaded at the kiln's front. Fuel is fed through a burner. These kilns offer thorough calcination, uniform quality, high quality, high production capacity, high operating efficiency, and ease of operation.

Highlights

1. Rotary kilns offer flexible configuration and a wide range of sizes, making them suitable for large, medium, and small-scale titanium dioxide production.

2. The kiln is an open-type calcination system with a simple kiln structure, uniform heating, stable product quality, and low rates of under- and overburning.

3. A vertical cooler or single-drum cooler at the kiln's front cools the titanium dioxide, recovering waste heat and facilitating transfer and transportation to the next production stage.

4. Equipped with a variable frequency speed motor, the drum speed is easily controlled, effectively controlling material residence time, stabilizing thermal conditions, and ensuring product quality.

Operating Principle

The salt-treated metatitanic acid slurry or pellets are fed into the kiln at the rear end. Due to the inclination and slow rotation of the rotary kiln, the material moves in a circular motion within the kiln, tumbling continuously while simultaneously moving toward the kiln head. Fuel is fed and combusted at the kiln head. As the material moves toward the kiln head, it exchanges heat with the hot air, completing the drying, desulfurization, crystal transformation, and particle growth processes. It is then calcined into titanium dioxide and discharged from the kiln head.
