Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...
The use of cement in Mexico dates to the end of the nineteenth century. By the 1920s, cement was the material of choice, not just for the exterior of the home but also for some interior furniture. Maybe that is because it is one of the most economical construction materials or because it can withstand earthquakes.
History of Portland Cement • First rotary kiln designed to produce Portland cement patented in 1885 by Frederick Ransome. • First economical U.S. kilns developed by Atlas Cement Company in 1895. • Thomas A. Edison first developed long kilns (150 feet compared to 60 to 80 feet).

The Cement Manufacturing Process. Cement is created by heating crushed limestone with clay, slate, blast furnace slag and other materials, then cooling and grinding the resultant clinker to create a fine powder. Most modern cement plants use a dry process which is more thermally efficient than the older wet process.
The process involves feeding the raw materials into a cement ball mill or vertical roller mill, where they are ground into a fine powder. ... The purpose of cement milling is to reduce the size of the clinker and other raw materials to achieve a specific particle size distribution that allows for the desired physical properties of the cement ...
