The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form …
Manufacturing
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.

What is the manufacturing process of Portland Cement?
William Aspdin made what could be called 'meso-Portland cement' (a mix of Portland cement and hydraulic lime).Isaac Charles Johnson further refined the production of 'meso-Portland cement' (middle stage of development), and claimed to be the real father of Portland cement. In 1859, John Grant of the Metropolitan Board of Works, set out …
Digitization and the future of the cement plant | McKinsey
There's never been a more important time to build resilience into the core of the cement value chain: the cement plant. The cement industry is being hit hard by the COVID-19 pandemic, with global demand for cement expected to decline by 7 to 8 percent in 2020—though these declines have been unevenly distributed across regions. 1 Paul …
Cement: Materials and manufacturing 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 mudstones.
