How To Choose Best Raw Material For Cement Industry


Cement-producing could be an advanced method that begins with mining then grinding raw materials that embrace sedimentary rock and clay to a fine powder, known as raw material, that is then heated to a very high temperature as high as 1450 °C in an exceeding cement oven.


Which material is used in the cement industry?

The most common raw materials for cement are sedimentary rock, clay, and dirt. These are the requirements used by blasting or splitting exploitation serious machinery. Raw materials used for producing Portland cement are usually found naturally within the earth’s crust. It’s created primarily from chalky and clayey materials and minerals. Chalky materials contain sedimentary rock or chalk, whereas clayey materials include relationships with silica-alumina and iron. Each area unit is found as clay or sedimentary rock.


 The common material in cement production is minerals containing calcined lime, silex, aluminum, and iron oxide. Limestone. Makes hardness is 1.8-3.0. The older the earth science fraction, the firmer.

The most common and best raw material cement industry is:

  • Limestone (supplies the majority of the lime)
  • Clay, dirt, or sedimentary rock (supplies the majority of the silicon dioxide, aluminum oxide, and ferrous oxide)
  • Other supplementary materials like sand fly ash/pulverized fuel ash (PFA) or ironstone to attain the required bulk composition


‘Portland’ is the most generally made cement. The name comes from its similar to Portland stone. Other cements include rapid-hardening, low-heat, sulfate-resisting, and low-alkali.




Increasingly cement blocks are mixed with ‘cement substitutes’ like fine-grained Fuel Ash (PFA), ‘Fly ash,’ and Ground coarse Blast-furnace scum (GGBS). The blends aim at reducing the environmental impact of the exploitation of 100% cement. In addition, it can improve stability strength, be long-lasting, and easier to work.

Building management is associate degree art; most buildups can most likely have “good material” from that cement will be created. However, they’ll even have some material that’s not pretty much as good. This may be more durable to grind or be of less convenient composition.

Once the raw materials are ground fine enough, they’re mixed within the proportions needed to provide the required composition.


The mixing of raw materials is kept in an operating bubble before being fed into the oven. The bubble gets stored for many days’ offer of fabric a barrier against any glitches within the supply of material from the buildup.


Technically, a cement producer will have almost complete management over the back stone of the cement production composition by mixing raw materials of various compositions to provide the required result. However, clinker composition is essentially determined by the locally-available raw materials that form up the majority of the raw material.


Supplementary materials area unit won’t change the composition of the raw material. However, price and accessibility are possible to how much they’re used. Transport prices particularly become visible due to the massive quantities of materials used in creating cement.
