The cooling zone is the part of the kiln where the sintered dolomite emerging from the reaction zone is cooled before discharge from the bottom of the kiln. The considered shaft kilns in this ...

Shaft kiln's small floor space. The vertical kiln is arranged upright. The single-hopper hoist is arranged at a large angle, and the functional areas are compactly arranged to greatly reduce the floor space. Shaft kiln's less investment. The kiln steel structure has fewer machining parts and lower processing costs.

As with the PFR kiln, the kiln charge consists of crushed and screened limestone or dolomite. The grain sizes are typically 40 to 80 mm or smaller. The kiln shafts are also completely filled with the material to be processed but the kiln charge passes the lime kiln at a higher speed - typically two meters per hour.
