Vertical Lime shaft kiln is a fixed steel vessel kilns where the raw limestone of required sizes is fed from the top of the vertical lime kiln, from where it will move downward by gravity through all these zones known as the preheating, calcining, and cooling zones to become converted into fully burnt lime.Kilns to produce cement are almost equally old. Now cement kilns can be divided mainly into 2 types: vertical shaft kiln and rotary kiln. The vertical kiln is the older type and its origin dates back to the 5th century AC. Rotary kilns were first used in 1880. Around the 20th century, they replaced vertical shaft kilns almost everywhere. 3.
