Cement was traditionally made from raw materials that included limestone, shells or chalk, shale, clay, sand and iron ore. Today, cement is mixed using calcium, silicon, aluminum and iron, in addition to the quarried clay. Water is added to the mixture to create a hard building material. The largest producer of cement is China, followed by India and the United States. China will dramatically increase production due to economic factors creating a building boom in the country.
Cement Production Method
Cement is produced in either a dry or wet process. The dry process takes quarried clay that is first crushed into 5-inch pieces and then crushed again into pieces 3/4 inch in size. The dry material is then crushed into a powder blend and dried in a kiln. The wet process applies water to the crushed clay mixture. This slurry is then dried in a rotating kiln that is used to fuse the mixture together. The hot solid is next cooled, mixed with gypsum and then ground. Most cement is currently created using the dry process due to the ease of production and the energy savings over cement produced using the wet process.
Small Cement Production Line
Cement production process involves raw materials extraction and handling, kiln feed preparation, pyroprocessing, and finished cement grinding etc. An integrated cement plant that prepares the raw mix, feeds it to the pyro-processing system, and then grinds the clinker from the kiln system into various cement products. Most cement plants have quarries located nearby to supply the limestone and other raw materials.
There are large number of small cement production line operated all over the world. All cement plants with a capacity of 200 tonnes per day or less are classified as small cement production line. The small cement plant project cost is affordable for small scale operators. It is available with crusher plant, mini cement grinding mill, ball mill, vertical roller mill, rotary kiln etc.
