FETTLING OF THE ROTATING KILN Russian patent published in 1995 - IPC

FIELD: manufacture of building materials. SUBSTANCE: fettling of the rotating kiln has a heat-insulating layer of bricks 2 stacked in cylindrical housing 1 made of steel. Bricks 2 of the fettling are held together by binding material 4. The improvement of the kiln performances is achieved by the fact that the heat-shielding layer in the form of separate fire-proof tiles 3 is placed on the working area of the fettling. Holders 5 are fixed between the bricks on binding material 4. They restrict the tile displacement. It results in restraining the destructing thermal and chemical influence of the technological process on the fettling bricks. The fettling stability increases twice and more. EFFECT: improved performances of the kiln. 1 dwg
