The silo stores several days' supply of material to provide a buffer against any glitches in the supply of raw material from the quarry. Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result.
The capital-intensive cement industry needs to secure valuable deposits over the long term. Close geographical links between cement production and mining sites is also extremely important. Short routes for supply of raw materials take pressure off of traffic volumes and
The main materials used in cement production are minerals containing calcium oxide, silex, alumina and iron oxide. These components are rarely found in one type of raw material; therefore, for the cement production the raw mix is selected for the following components:
This makes the cement sound if present in small quantity but an excess can make the cement unsound. Cement is sometimes blended with other cementitious and/or a special material. This cement is called blended cement. They are produced by properly blending two or more types of cementitious materials and cement raw materials.
Cement Production: Raw Meal Production in Steps Perfectly mixed, accurately fed without pulsation, and precisely weighed. The key word is quality! And this quality is achieved during cement production with exactly matched process steps. In the first stage, the raw meal is produced, as described below.
Mostly lime stone, then depend on what you intend to make, other minerals like bauxite, iron, pozzolanic, etc. Most of the cement function came from calcium trisiligate and tricalcium alminate which found in line stone but secondary material often...
The finely ground raw material or the slurry is fed into the higher end. At the lower end is a roaring blast of flame, produced by precisely controlled burning of powdered coal, oil, alternative fuels, or gas under forced draft. As the material moves through the kiln, certain elements are driven off in the form of gases.

Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement. The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone. Clayey raw material

Raw material extraction and production of raw meal For cement production, limestone, clay and other treasures from the depths of the earth are needed. We produce these raw materials as gently as possible, consider our environment and, as regional specialists, are able to keep transportation routes short. Our plants are ISO-certified and are thus
The main raw material used in cement production has traditionally been limestone. Limestone is abundantly available, but over 60% of the industry’s CO 2 emissions are caused by transformation of limestone into lime, called “decarbonation”. Accordingly, part of the route towards a low carbon concrete-built environment can involve limestone substitution.
