Steps involved in
cement manufacturing process
Basically cement is a quality rated material which is greatly
compatible to Eco system of earth and mainly adaptable to the sustainable
development. It is basically a fine powder that gets sets on its own after some
hours, if mixed properly with some water. It gets converted in solid matter as
a strong material afterwards. The cement material is used for binding the
coarse aggregates and fine sand together in a concrete. The cement is known as
hydraulic binder which gets harder after getting mixed with water. The Portland
cement was invented in 1824 by the Joseph Aspidin who is known as the
bricklayer or Leeds builder widely.
The cement manufacturing process by Aspdin
Under the process generated by the Aspdin, he mixed well the
ground harder limestone and divided the clay in calcined and slurry similar to
lime kiln, until the carbon di oxide gets expelled. The calcined mixture
grounded in fine powder was used and known as Portland cement further. The
cement named as Portland originated from the natural stone which is in England,
called largely as Portland. The Portland cement first got produced in the year
1904 in Chennai, near Madras by the south Indian Industries Ltd and further it
got developed by Indian cement Ltd in 1914. Presently the cement price worldwide is pretty much affordable, and moreover the
price range and quality of cement differs from company to company.

The basic components or raw materials used in cement manufacturing process
·
Limestone
·
Clay
·
Bauxite
·
Iron
core
Under the process of cement making,
the mixing composition of such raw materials include the following
·
Limestone:
90-93%
·
Clay
2-3%
·
Bauxite
2-3%
·
Iron
ore: 1-2%
The various steps involved in cement manufacturing process
Mining of limestone
1.
the
preparation of raw materials
2.
Crushing
of raw materials in proportionate amount, its blending, grinding and storing
3.
The
burning of the raw mixture
The most used and common method of manufacturing the Portland
cement is making use of dry method. Under this, the raw materials get quarried
as clay, limestone and other materials. After its quarrying, the rock gets
crushed which involves different stages, the crushing lessen the rock size to
about 6 inch and further that rocks gets a secondary crush or used in hammer
mill for reducing more its size to 3 inches or more. The crushed rock can be a
combination of other components as fly ash, iron ore, mixed, ground % fed to
cement kiln.
The cement price
keeps on fluctuating as well. The different companies engaged in the process of
cement manufacturing fixes their cement prices after complete production. It
even varied according to city, state or region. The cement is considered as the
important factor for building any house, bridges, flyovers, residential building,
office space and much more. Without it, no construction can be done, thus and
known as critical for the construction industry which gets hardens, if mixed
properly with water.
