Vertical shaft kiln is a kind of vertical cement kiln, the kiln body is upright on the ground and can not rotate. Materials in the kiln move from top to bottom, and the combustion-supporting air flows from bottom to top. The heat carried by the high-temperature materials will preheat the combustion-supporting air, which reduces the heat loss.
