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 been largely replaced by rotary kilns, which were implemented for the first time in 1880. ...

We have introduced the refractory materials applicable to each part of the cement rotary kiln, but to decide which kind of material is the best one to be used as the refractory lining for a certain part of the kiln, we still need to refer to the overall situation of the specific project, and consider the production environment, investment cost ...
Vertical shaft kilns have among others the advantage of low investment profile and hence very suitable for small and medium scale processing of various solid minerals such as limestone and refractory. The low investment profile therefore makes it attractive in developing countries where sources of investment capital are lean.
simulation of thermodynamic processes of vertical shaft kiln used for producing deadburned magnesia is presented. The model developed is a 2D steady state model. The combustion, particle-gas dynamics and heat transfer processes which occur inside a vertical shaft kiln are modeled by Eulerian multiphase model, and Species transport and

The length of each part of a rotary kiln is designed based on the inner diameter (D) of the kiln shell.. 1) The length of the kiln head overhanging section (l 1): l 1 = (1.2~1.5) D. As the first section of a rotary kiln, l 1 is better not to be designed too long, or the length of the effective parts of the kiln will have to be shortened.. 2) The length of the preheating …
