A method and apparatus for producing cement which includes intermixing the cement forming raw materials with water, coal or coke and cement as a binder and forming this mixture of materials into nodules by pelletizing or extrusion. The system is particularly designed for use in making white cement where raw materials low in coloring compound are used as raw feed.

Learn MoreIt is worth mentioning that in crushing and grinding clinker (to turn it into cement) to whiten the color of cement and also to increase the strength, some gypsum powder is added to it. Consumption of this type of cement is limited to the need for white or light facade and is generally used in conjunction with cement clinker price aggregates.
Learn MoreGrinding of cement clinker together with additives to control the properties of the cement is done in ball mills, roller mills, or roller presses.

Learn MoreComposition. This product is manufactured by grinding a blend of white clinker, selected limestone and calcium sulfate as setting regulator. White clinker is produced by a specific process from selected raw materials with very low content of metal oxides, particularly iron oxide. The main characteristic of this product is its high whiteness index.
Learn MoreCement is made by grinding clinker—the main energy intensive ingredient—to a fine powder. Producers know that replacing some of the clinker in portland cement with ground limestone offers benefits, the most important being that it reduces the embodied CO2 of the cement.

Learn MoreCement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed are difficult to grind.
Learn MoreFrom the early 1900s, both for cement grinding and for grinding hard raw materials, whether by wet or dry process, the standard arrangement was a ball mill for preliminary grinding (to below mm), followed by a tube mill for fine grinding. Typically the ball mill was placed on an upper floor so that material could move by gravity. An example was the original rawmill system at …

Learn MoreThey are similar to those of Portland blast-furnace cement. 8-White Cement White Portland cement is made from raw materials containing very little iron oxide (less than % by mass of clinker) and magnesium oxide (which give the grey color in ordinary Portland cement). China clay (white kaolin) is generally used, together with or limestone.
Learn MoreAfter the clinker is cooled, cement plants grind it and mix it with small amounts of gypsum and limestone. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects (Fig. below).

Learn MoreOn grinding clinker, alite is brittle and breaks easily. Belite, on the other hand, is tougher (although not necessarily much harder) and tends only to deform on impact. The aluminate and ferrite are also somewhat harder. For this reason, breakage of clinker particles occurs mainly through the alite crystals, so that polymineralic cement particles have mainly alite exposed on …
