Vertical Shaft Kilns (VSK) vs. Rotary Kilns
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 ...
