Powder Rotary Kiln

The structure of the titanium dioxide calcining kiln is similar to that of the rotary kiln in the alumina, cement and other industries, and its cylinder is rolled by steel plate, and is inlaid with refractory lining, forming a specified Angle with the horizontal line. The cylinder body is covered with three rectangular wheel belts supporting each support device. A large tooth ring is fixed on the cylinder near the middle wheel belt with a tangential spring plate, and a small gear engages with it at 300 places below it. During normal operation, the main drive motor transmits power to the open gear device through the main reducer to drive the rotary kiln.

Information

The main working principle of titanium dioxide kiln is: input the filtered titanium dioxide hydrolyzed cake into the tail end of the titanium dioxide rotary kiln body with a certain slope and slow rotation (the high-end of the cylinder), while the combustion mixing chamber in the direction of the kiln head (the low-end of the cylinder) blows the clean flame and hot air into the kiln to dehydrate and calcination the filter cake. The hydrolyzed titanium dioxide cake after dehydration and calcination at a high temperature of more than 1000 ° C, with the help of the tilted titanium dioxide rotary kiln body, both rolls in the circular direction and moves along the axial direction (from high-end to low-end), constantly completing the process of dehydration and calcination. Finally, the cooling machine is entered through the double hydraulic flip plate discharge valve at the lower part of the kiln head cover, and the material after cooling and screening is the finished titanium dioxide.
