In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature (2,500 to 2,800 degrees Fahrenheit) in a rotating kiln, then grinding the clinker to a fine powder. The heating that occurs in the kiln transforms the raw materials into new chemical compounds.

Rotary kiln Wikipedia

The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its longitudinal axis. The process feedstock is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down toward the lower end, and may undergo a certain amount of stirring and mixing.

Explained: Cement vs. concrete — their differences, and

Apr 03, 2020 Cement production begins with limestone, a sedimentary rock. Once quarried, it is mixed with a silica source, such as industrial byproducts slag or fly ash, and gets fired in a kiln at 2,700 degrees Fahrenheit. What comes out of the kiln is called clinker. Cement plants grind clinker down to an extremely fine powder and mix in a few additives.

Manufacturing of Portland Cement Process and Materials

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 nodular shaped clinker by broking of
