Verification of Raw Materials in Cement Production by FT-IR. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. The identity and quality of the ingredients used must be clearly established in order to deliver the optimal product.

cement - 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.

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. In this process, the chemical bonds of the raw materials are broken down and then they are ...

The choice of composition of materials mixture with useful components generally is determined by plant's geographical location and delivery of raw materials. The only common feature in all cement production plants is the difficulty of grinding the source material as the material is hard enough and has high abrasiveness.

the cement industry planning process is centralized and optimization oriented. There is no constraint in the availability of cement main raw materials with the exception of some countries where subsoil ownership regulations applied. Cement manufacturing is capital and energy intensive where cement truck delivery is restricted due to its low

Lime Component Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and chalk.Limestone is of predominantly fine grained crystalline structure, its hardness is between 1.8 to 3.0 of the Mohs scale of hardness and specific gravity 2. To 2.8. Limestone usually contains admixtures of clay substance or iron compounds, which influences its color.

Limestone comprises 95% of core raw material for cement production. No wonder then that the cement sector governs demand, supply and pricing of limestone (as well as coal) to some extent. According to some estimates, around 180-250 kg of coal and about 1.5 tonne of limestone is required to produce a tonne of cement.

Milling and grinding of raw material, minerals and cement is a rough process, with highly abrasive and hard feed materials that can accelerate equipment wear and tear. This leads to increased costs for equipment and spare parts replacement, and costly maintenance.
