The shaft refers to a vertical vessel where the calcining takes place. Because of the weight of the bed of material in the shaft, there are limits on the size and strength of the type of limestone that can be calcined. Vertical kilns work on a batch-type system rather than continuous feed, and the upper kiln area is used for preheating.

Advantages and disadvantages of Vertical Shaft Lime Kiln
Abstract. The calcination principle of composite firing shaft kiln is: mix the solid fuel (coke or anthracite) with qualified stone evenly, use rotary discharging device equipped on kiln roof to discharge the mixture into the kiln, then under its own gravity the mixture proceeds through preheating area, calcining area, cooling area, and finally calcined into qualified finished lime product.
