Vertical Kilns 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.
The plant currently operates only the Kiln 3 production line – a four-stage configuration with in-line pre-calciner. The kiln features indirect firing with a multi-channel burner. Fully integrated plants. Among the key elements of current plant operations at Dudfield are two coal mills and two cement mills.
For more than 100 years, FL has been delivering cement kilns that are tested, reliable, and require minimal energy and space. Our cement rotary kilns deliver high production capacity with long lifespans and low maintenance. And now, with online condition monitoring services, we can optimise kiln performance even further and help …
Water evaporation In wet-process kilns, and their derivatives, water must first be driven off. In a wet-process kiln, calcining takes place after the water has been driven off, about a third of the way down the kiln. In the more modern pre-calciner kilns, the feed is calcined prior to entering the kiln.
