Titanium dioxide rotary kiln

The structure of titanium dioxide rotary kiln is similar to that of rotary kiln in alumina, cement and other industries. Its cylinder is rolled up by steel plate and is lined with refractory lining, forming a prescribed angle with the horizontal line. The cylinder body is sleeved with three rectangular wheel belts to support each supporting device. A large gear ring is fixed on the cylinder near the middle wheel belt with a tangential spring plate, and a pinion meshes with it at the lower 3O. In normal operation, the main drive motor transmits power to the open gear device through the main reducer to drive the rotary kiln.

Main working principle of titanium dioxide rotary kiln:

The filtered titanium dioxide hydrolysate cake is fed into the tail end of the rotary kiln with a certain slope and slow rotation (the high end of the cylinder). At the same time, the combustion mixing chamber with the direction of the kiln head (the low end of the cylinder) will blow clean flame and hot air into the kiln to dehydrate and calcine the filter cake. After dehydration and calcination at high temperatures above 1000 C, the hydrolyzed titanium dioxide filter cake is rolled along the circumference and moved along the axis (from high end to low end) with the help of tilted titanium dioxide rotary kiln body, and the process of dehydration and calcination is continuously completed. Finally, through the double hydraulic discharging valve at the lower part of the hood of the kiln head, it enters the cooler. The material after cooling and sieving is the finished product of titanium dioxide.
