Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.
Production of cement completes after passing of raw materials from the following six phases. These are.
Cement uses raw materials that cover calcium, silicon, iron and aluminum. nbspSuch raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay. Sand amp clay fulfill the need of silicon, iron and aluminum.evalewritetag250,250,engineeringintrocom-box-3,eslot3,107,0,0.
Generally cement plants are fixed where the quarry of limestone is near bye. This saves the extra fuel cost and makes cement somehow economical.nbsp Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant.
There are also various other raw materials used for cement manufacturing. For example shale, fly ash, mill scale and bauxite. These raw materials are directly brought from other sources because of small requirements.evalewritetag468,60,engineeringintrocom-medrectangle-3,eslot11,108,0,0.
Before transportation of raw materials to the cement plant, large sie rocks are crushed into smaller sie rocks with the help of crusher at quarry. Crusher reduces the sie of large rocks to the sie of gravels.
The raw materials from quarry are now routed in plant laboratory where, they are analyed 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.evalewritetag250,250,engineeringintrocom-medrectangle-4,eslot12,109,0,0.
Now cement plant grind the raw mix with the help of heavy wheel type rollers and rotating table. Rotating table rotates continuously under the roller and brought the raw mix in contact with the roller. Roller crushes the material to a fine powder and finishes the job. Raw mix is stored in a pre-homogeniation pile after grinding raw mix to fine powder.evalewritetag336,280,engineeringintrocom-box-4,eslot4,110,0,0.
After final grinding, the material is ready to face the pre-heating chamber. Pre-heater chamber consists of series of vertical cyclone from where the raw material passes before facing the kiln. Pre-heating chamber utilies the emitting hot gases from kiln. Pre-heating of the material saves the energy and make plant environmental friendly.
Kiln is a huge rotating furnace also called as the heart of cement making process. Here, raw material is heated up to 1450 C. This temperature begins a chemical reaction so called decarbonation. In this reaction material like limestone releases the carbon dioxide. High temperature of kiln makes slurry of the material.
