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.
Process manufacturing is a branch of manufacturing that is associated with formulas and manufacturing recipes, and can be contrasted with discrete manufacturing, which is concerned with discrete units, bills of materials and the assembly of components.
The portland cement manufacturing industry is relying ... The heart of the portland cement manufacturing process is the pyroprocessing system. This system transforms the raw mix into clinkers, which are gray, glass-hard, spherically shaped nodules

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.
Cement production is an energy intensive process, with energy costs representing 20-40% of production costs (IEA, 2007. p. 145). Since 1990s, globally there has been a gradual reduction in the "clinker ratio" – the ratio of clinker to cement in the final product – which reflects in reduced specific energy consumption.
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.

Methods of cement manufacturing 1- Wet process ___ grinding and mixing of the raw materials in the existence of water. 2- Dry process ___ grinding and mixing of the raw materials in their dry state. The process to be chosen, depend onthe nature of the used raw materials.
Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.

The Cement Manufacturing industry produces a wide range of cements, including Portland, hydraulic and aluminous cements, as well as cement clinker and hydraulic lime. Cement is used predominantly in concrete products, with demand from ready-mixed concrete accounting for a large percentage of revenue.
From the limestone quarry to the delivery of the end product, follow every step in the cement manufacturing process. Step 1: extraction of raw materials The raw materials needed to produce cement (calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay.
The cement industry produces about 10% of global man-made CO 2 emissions, of which 60% is from the chemical process, and 40% from burning fuel.  Nearly 900 kg of CO 2 are emitted for every 1000 kg of Portland cement produced.
