  • Cement Raw Materials used in Manufacturing of Cement

    2020-7-15  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.

They are then crushed and transported to the plant where they are stored and homogenized.

  • CEMENT RAW MATERIALS - International Cement Review

    2013-6-9  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

  • How Cement Is Made

    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.
