At the lowest limit imposed by cement standard specification, it could be possible that there is no sufficient scope left for an extensive sulfatizing of the alkalies. Chloride. The chloride content of German cement raw mix fluc tuates generally between 0.01 and 0.1% by weight, sometimes rarely over 0.3% [7a].
Generally cement plants are fixed where the quarry of limestone is near bye. This saves the extra fuel cost and makes cement somehow economical. Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. There are also various other raw materials used for cement manufacturing.

Cement production has undergone a tremendous development from its beginnings some 2000 years ago. While the use of cement in concrete has a very long history, the industrial production of cements started in the middle of the 19th century, first with shaft kilns, which were later on replaced by rotary kilns as standard equipment worldwide.
Cement is a key ingredient in concrete, which is used to build everything from houses and bridges to sidewalks and sewer systems. Concrete is made by mixing cement with …
Cement rotary kiln is the core equipment of cement plant, mainly responsible for clinker calcination, which can be used both in dry process cement production line and wet process cement production line. It is usually placed horizontally and at an angle to the ground, forming a state of one end high and one end low. ...
