A brief information about the process of Cement Production.

Dry, semi-dry, semi-wet and wet processes are the four main process routes that are used for the production of cement. Dry processes are considerably more energy efficient but the choice of technology mainly depends on the state of raw materials.

Cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.

The cement industry in particular, due to its nearly global presence and its process-inherent advantages, lends itself particularly well to co- processing such materials.

Successful cement production starts with the raw materials and the methods needed to process it. Vertical mills grind the raw powder to the correct fineness before it is subsequently burned in the rotary kiln to produce clinker.

This statistic shows the worldwide cement production, by major producing countries, from 2012 to 2017. In 2017, cement production in the United States amounted to some 86.3 million metric tons.

Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.

The entire manufacturing process in a modern plant is now controlled through a microprocessor based programmable logic control system to maintain uniform quality of cement and a high rate of production.

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.
