Optimum performance oriented and application specific design.Single shaft type, high performance and mix fire kiln system from kinc adds enormous advantages to lime | dolomite industry. Effective and economic way for lime and dolomite calcinations.

In a shaft kiln, the limestone | dolomite moves counter flow to hot gases in the shaft. This gives shaft kilns the lowest fuel consumption of any type of calciner. 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.

Application

Vertical kilns work on a batch-type system rather than continuous feed, and the upper kiln area is used for preheating. Typically, the kiln would be shut down, the batch would be charged and the burners would be re-fired. The calcined limestone is then removed from the bottom of the kiln through a cooler system at a controlled rate.
