Cement Production an overview ScienceDirect Topics

The clinker is a kiln outlet, which is the main cement ingredient The limestone is used only for the cement production, for certain cement types, in the cement mill as a mineral component. The raw materials from the depo centre are transported to the vertical roller mill, where raw meal is produced. The storage of this raw meal consists of 2 silos.

and alumina. 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.

Rawmill Wikipedia

A rawmill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement.Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The rawmilling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the

Different Possible Ways for Saving Energy in the Ce ment

In terms of absolute consumption, the cement industry occupies a front position in the ranks of energy consumed industries. The total energy costs (thermal and electrical) make up about 30 to 40 percent of the total production costs of cement. This is why efficient energy utilization has always been a matter of priority in the cement industry.
