2.4 Cement production using Vertical Shaft Kilns. The raw materials used for cement production in Vertical Shaft Kilns (VSKs) are. exactly the same as in any other production process, i.e. limestone/chalk, marl, and clay/shale. These raw materials are extracted from quarries which, in most cases, are located close to the. cement plant.
Finally, the clinker is taken out of kiln bottom. Cement Mill and Finishing Thus the clinker formed in Vertical Shaft Kiln will be fed into the cement mill hopper by means bucket elevator where 2% Gypsum will be added and fed to the ball mill for grinding operation.
