burning process of portland cement

Manufacture of Portland Cement: 3 Processes

Portland cement can be manufactured by intimately mixing together calcareous and argillaceous stones containing silica, alumina, and iron oxide etc. and burning it in large rotary kilns at a temperature of approximately 1400°C to 1500°C. At his temperature the materials partially fuse, forming clinker.

What is the manufacturing process of Portland

Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration. This is a complex process that is best understood by first understanding the chemical composition of cement. Manufacture of cement. Portland cement is manufactured by crushing, milling and proportioning the following materials:

Reactions in the cement kiln - clinkering

Evaporation of volatiles Volatile phases in the cement kiln are principally alkali sulfates, with a much smaller proportion of alkali chlorides. As the part-burned feed approaches the burning zone, these volatile phases are in liquid form and a proportion volatilizes, the remainder passing out of the kiln in the clinker as inclusions within the pores.

Cement kiln - Wikipedia

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

The Process for Making Portland 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.

How Cement Is Made - Portland Cement

Bricklayer Joseph Aspdin of Leeds, England first made portland cement early in the 19th century by burning powdered limestone and clay in his kitchen stove. With this crude method, he laid the foundation for an industry that annually processes literally mountains of limestone, clay, cement rock, and other materials into a powder so fine it will pass through a sieve capable of holding water.

15-03-2017  Raw materials are homogenized by crushing, grinding and blending so that approximately 80% of the raw material pass a No.200 sieve. The mix will be turned into form of slurry by adding 30 – 40% of water. It is then heated to about 2750ºF (1510ºC) in horizontal revolving kilns (76-153m length and 3.6-4.8m in diameter.

How Portland Cement is Made? Manufacturing

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. Slag and fly ash can also be added to

Reactions in the cement kiln - clinkering

In the burning zone, above about 1300 °C, reactions take place quickly. The clinker is in the burning zone for perhaps 10-20 minutes but in this time a lot happens: The proportion of clinker liquid increases and nodules form. Intermediate phases dissociate to form liquid and belite.

Microwave-promoted burning of Portland

01-01-2002  A new method of burning Portland cement clinker is studied. The microwave sintering is adopted after the raw meal is heated to certain temperature in an electric furnace. The experimental results show that after the raw meal is heated at a low electric heating temperature (1000–1200 °C) and then further sintered with microwave for 1 to 2 min, Portland cement clinkers can be formed.
