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.
In a shaft kiln, the limestone | dolomite moves counter flow to hot gases in the shaft. This gives shaft kilns the lowest fuel consumption of any type of calciner. The shaft refers to a vertical vessel where the calcining takes place.
According to different types of shaft kilns, we can adopt coal, coke, natural gas, coke oven gas, blast furnace gas, diesel oil, etc., as the burning fuel. Small …
