2. Raw meal production The crushed limestone is ground into raw meal. Additives such as clay, sand or iron ore result in the desired chemical composition. The MULTIDOS® H weighfeeders and MULTIDOS® VPD apron feeders feed the various materials into the raw mill accurately and reliably. The raw meal is then homogenised in the blending silos.
Material Handled 585 – 620# raw material yields 1 BBL cement (376#) or average ratio : 1. Aerial view of typical cement plant. This plant now houses three 9½'' x 25′, an 8½'' x 7′, three 8½'' x 6′ and one 9½'' x 9′ Grate Discharge Ball Mills and one 9½'' x 12′ Open End Cement Rod Mill.
Now the raw materials are mixed in specific proportions so that the average composition of the final product is maintained properly. Fig: Manufacture of Cement by Dry Process. b) Wet Process. The raw materials are firstly crushed and made into powdered form and stored in silos.

Chapter 1 Introduction to Cement Production The balance of cement used today consists of masonry cement, which is fifty ...There are two types of raw materials which are combined to make cement: ...The mixture of materials is finely ground in a raw resultant raw mix is burned in a rotary kiln at temperatures around 4482 degrees Celsius to form clinker.
The raw mix is fed into a circular storage unit called a raw mix storage. Then, the mix is extracted transversely from the stockpile by reclaimers and conveyed to a raw mill bin called the raw mix bin for grinding. The other raw materials that are used in cement manufacturing, called additives, are high purity limestone, sand and iron ore.

Aug 17, 1971· Portland Cement Manufacturing Process Description17 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrites. More than 30 raw materials are known to be used in the manufacture of portland cement, and these
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
preheater is diverted back to the raw mill for drying the raw material. The balance part of the hot gas is venting out to the atmosphere. This gas contains lot of fine material and has a temperature around .
