Vertical Shaft Kiln Why They Are Diminishing AGICO ...

Vertical Shaft Kiln Structures Working Principles. In cement plants using vertical kilns, the grinded raw materials are first made into wet pellets by adding 12-14% water to the pelletizing pan of the disc pelletizer.Then the wet pellets are fed from the kiln top and discharged from the bottom after calcination.

Vertical Shaft Kiln Vs Rotary Kiln - Reitzindia

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 5 th century AC. Rotary kilns were first used in 1880. Around the 20 th century, they replaced vertical shaft kilns almost everywhere.
