Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.

Cement manufacturing process is mainly divided into three stages, namely, raw meal preparation, clinker burning and cement grinding. Generally speaking, the cement industry production is Portland cement. Portland cement is a kind of delicate, usually gray powder, which consists of calcium (from limestone), silicate, aluminate and ferrite (clay).

Portland cement can be made by following two different processes – a dry one and a wet one. Joseph Aspdin first made portland cement in his kitchen stove in England in the 19th century. Lime and silica make up approximately 85% of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore.

Cement Manufacturing Process Phase II: Proportioning, Blending Grinding. The raw materials from quarry are now routed in plant laboratory where, they are analyzed and proper proportioning of limestone and clay are making possible before the beginning of grinding. Generally, limestone is 80% and remaining 20% is the clay. Proportioning of raw material at cement plant laboratory. Now cement ...

The Process for Making Portland Cement Materials that contain appropriate amounts of calcium compounds, silica, alumina and iron oxide are crushed and screened and placed in a rotating cement kiln. Ingredients used in this process are typically materials such as limestone, sandstone, marl, shale, iron, clay, and fly ash.

PROCESS OF MANUFACTURING OF CEMENT • The process of manufacturing of cement consists of grinding the raw materials, mixing them intimately in certain propor- tions depending upon their purity and composition and burning them in a kiln at a temperature of about 1300 to 1500 C, at which temperature clinkers are formed and they are made into fine powder in addition with 3 to 5% of gypsum to form

The heart of the portland cement manufacturing process is the pyroprocessing system. This system transforms the raw mix into clinkers, which are gray, glass-hard, spherically shaped nodules that range from 0.32 to 5.1 centimeters (cm) (0.125 to 2.0 inches [in.]) in diameter.


There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as “clinker,” together with some 5 percent of gypsum (to control the time of set of the cement).

The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km. The limestone is excavated from open cast mines after drilling and blasting and loaded onto dumpers which transport the materials and unload into hoppers ...

Must Read: Dry Process For Manufacturing of Cement. When lime stone is used, first blast it, then crushed in two progressively smaller crushers and then fed into a ball mill with the clay dispersed in water. The resultant slurry is pumped in to storage tanks. The slurry is a creamy consistency liquid with 35 to 50 percent water content and some small fraction of material about 2 percent larger ...

Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called ...

The flowsheet diagram of the wet process for manufacturing Portland cement is given in Figure 3.3. The limestone is disintegrated in crushers. The crushed limestone is fed to tube mill, where the limestone and the clay, introduced as a slurry from a clay mixer, are simultaneously subjected to fine grinding.
