Wet process kilns The original rotary cement kilns were called 'wet process' kilns In their basic form they were relatively simple compared with modern developments The raw meal was supplied at ambient temperature in the form of a slurry A wet process kiln may be up to 200m long and 6m in diameter...
It was stronger than Portland cement but its poor water resistance and corrosive qualities limited its use in building construction The next development in the manufacture of Portland cement was the introduction of the rotary kiln, which produced a stronger, more homogeneous mixture and facilitated a continuous manufacturing process...
Cement is so fine that 1 pound of cement contains 150 billion grains The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process...
The wet process of cement manufacturing involves adding water to finely crushed raw material, such as limestone, clay or iron ore, in a proportion of 35 to 50 percent water to 50 to 65 percent raw material to make a slurry that is fed into a cement kiln, whereas no water is added in the dry process...
• Chalk is porous and often has high moisture content that leads it to its use in the ‘semi-dry/wet’ manufacturing process of making cement This particular process represents some 16% of total production Shale • Shale is a pure sedimentary rock made of very fine silt, clay and quarz Shale falls in the category of mudston...
