The application of breaking joints bricks installing process to huge rotary kiln linings

This paper introduces the construction technology which applies to lining masonry of large rotary kiln. Practice shows that breaking joints bricks installing process is better than rotary kiln linings bricks installation. Most traditional rotary kiln linings breaking joints bricks installing process must be with jack supporters. Huge pressing force of supporters will make the kiln shells elastic-deformation. As the supporters are removed, the shells will recover to original status, and the massive mechanical stress will be left in the lining, which will cause early damage oflining and reduction of service life. Some alumina refineries adopt distribution supporters to install breaking joints bricks for aluminum oxide clinker kiln linings, which has extended service life and has promotion value.
