Shaft kilns are vertical in design, upto 30 m (metres) in height and with a diameter of upto 6 m. For this type of kiln, the limestone is fed in at the top section of the kiln which progressively makes its way down through the different stages of the kiln until it is discharged at the bottom as lime.
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.
