Vertical kiln, also known as shaft kiln and bottle kiln, is a vertical continuous kiln consisting of a steel shell with a vertical axis and a refractory brick lining. The vertical kiln produced by our company is environmentally friendly during production, consumes less energy, and has a high degree of mechanization and automation. It is composed of a kiln body, a feeding device and a ventilation device. Compared with the same type, it has a smaller floor area and less capital investment.

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.
