Shale brick factory, in production, often pours bricks when drying them!

Is it a tunnel kiln or a secondary code burning wheel kiln? If it is a tunnel kiln, there may be something wrong with the air duct. Shale bricks should not be as wet as clay bricks, and shale bricks should not be inverted. Then the kiln section is too large and the air duct is unreasonable. Drying too fast can also cause embryo inversion. I suggest you find a better fireman to visit the scene.
