Product Advantages


Work Principle

Work according to the principle of countercurrent heat transfer. The materials in the kiln move from top to bottom, and the flue gas passes through the entire column from bottom to top. The materials are preheated, calcined and cooled in the kiln, which has strict requirements on the block size of the raw materials entering the kiln, generally 25-150mm, but it must be installed in stages. The ratio of the maximum block size to the minimum block size should not exceed 2-3mm.
