1 Annular shaft kilns Annular shaft kilns were developed in the 1970s to produce soft-burned lime in a single shaft kiln. To achieve this, a co-current burning zone is estab - lished in the lower part of the kiln. Compared with a Parallel Flow Regenerative (PFR) kiln, the shaft ge-ometry is much more complex. This can be seen in Figure 1 .

There are two main types of kilns to produce cement: the Vertical Shaft Kiln and the Rotary Kiln. The Vertical Shaft Kiln or VSK is probably the first type of kiln that was used and it can be traced back to the 5th century A.C. in Greece, when they were used for limestone calcining (Reiter, AC, 11/1997, p. 23). In the 20th century, they have ...
What is a vertical lime kiln? Vertical lime kiln, also called shaft lime kiln, is a type of shaft kiln specially designed for lime calcining. Compared with rotary lime kiln, it has low construction cost, but there are many shortcomings, such as low utilization coefficient (<50%), high energy consumption ( >160kg of coal is consumed per ton of lime to …
