Cement production, which is highly dependent on the availability of natural resources, will face severe resource constraints in the future. This is especially true for the cement industry in China.
In dry and semi dry processes for manufacturing of cement, the raw materials are crushed and fed in the correct proportions into a grinding mill. The raw materials are dried and reduced in size to a fine powder in to grinding mill. The dry powder is called the raw meal. The raw meal is pumped into a blending silo.
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.
(1)Crushing: In the cement manufacturing process, most material must be broken, such as limestone, iron ore, clay and coal etc. Limestone is the main raw material for cement production, each producing a ton of clinker needs about tons of limestone, more than 80% of raw material is limestone.

Primarily for cement grinding plants in India, coal (generally of bituminous grade) is used in the slagdryer. The wet slag arrives at the stack on wagons from some nearby steel plant, or it may be brought via a trolleysystem (primitive mode).
At present, about 78% of Europe's cement production is from dry process kilns, a further 16% of production is accounted for by semidry and semiwet process kilns, with the remainder of European production, about 6%, coming from wet process kilns.
Cement milling is in particular a highly energyintensive process, there are potential energy savings available through the use of Mill Control System. The MCS is a software system that draws conclusions about the quality levels of the production plant through a knowledgebased approach using current plant data (defined measured values).
Cement production in 1929 reached a peak of 7,369,000 barrels, fell to 2,973,000 barrels in 1933, and rose to 8,036,515 barrels from ten plants in 1945, when Texas was the secondlargest producer and consumer of cement in the United States.
