Cement kiln - Wikipedia

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

Portland cement - ScienceDirect

Jan 01, 2016  Portland cement is a complex product made from very simple and abundant materials: limestone and clay (or shale). Very precise proportions of these two basic materials have to be mixed with some additions to create a raw meal with a precise chemical composition; this will result in the production of clinker through the complex pyroprocessing presented in Figure 3.1.
