In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter, produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.

Cement manufacturing process & what is cement made of, it can be discussed conveniently under two headings: Selection of Raw materials and manufacturing methods. Raw Materials of Cement. Most important raw materials (what is cement made of) required in the manufacture of Portland Cement are: Limestone, Clay, Gypsum, Fuel, and Water (in wet method).

Aug 30, 2012· Cement Manufacturing Process Phase IV: Kiln Phase. Kiln is a huge rotating furnace also called as the heart of cement making process. Here, raw material is heated up to 1450 ⁰C. This temperature begins a chemical reaction so called decarbonation. In this reaction material (like limestone) releases the carbon dioxide.

These have been used for many years for the less exacting raw-milling process, but recently roller mills, in combination with high-efficiency separators, have been used for cement grinding. The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient.

11.6 Portland Cement Manufacturing 11.6.1 Process Description1-7 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

Kiln and Kiln Shells: - As a Cement kiln manufacturers we manufacture all type of process equipments including Vertical and roller Kiln and Shells - Kiln Shells is involved in the process of burning the raw mixture thereby resulting in the clinker. This clinker is then subjected to grinding to produce cement.

kiln dry as opposed to the older process in which it is mixed with water. Each process produces "clinker", which is then finely ground with gypsum to make cement powder. A breakdown of the production cost of cement is: energy 31%, raw materials and consumables 28%, production, labor and maintenance costs 30% and depreciation 11%.

Kiln and Kiln Shells: - As a Cement kiln manufacturers we manufacture all type of process equipments including Vertical and roller Kiln and Shells - Kiln Shells is involved in the process of burning the raw mixture thereby resulting in the clinker. This clinker is then subjected to grinding to produce cement.

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.

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.

In the next state of the process, clinker is cooled in coolers. The hot air from the coolers is returned to the pre-heater in order to save fuel in the overall process. The clinker is then ground to produce portland cement. Gypsum is added during the grinding process to control the set rate of the cement.
