Cement Plant
Acement is a binder, a substance that
sets and hardens independently, and can
bind other materials together. A portland
cement is the most common type of cement
in general use around the world because it is
a basic ingredient of concrete, mortar, stucco
and most non-specialty grout. It is a fine
powder produced by grinding Portland
cement clinker, comprised of dicalcium
silicate, tricalcium silicate, tricalcium
aluminate, and tetracalcium aluminoferrite,
with the addition of forms of calcium sulfate.
Different types of portland cements are
created based on the use and chemical and
physical properties desired.
Manufacturing Process:
1. Crushing & Proportioning:
Limestone rock is the principal raw material,
the first step after quarrying in the processes
is the primary crushing. Mountains of rock
are fed through crushers capable of handling
pieces as large as an oil drum. The next step
in the process is to grind the above particles
to a size of 90 microns or less which is done
in a raw mill.
2. Pyro processing:
Next, the fine powder is heated as it passes
through the Pre-Heater Tower into a large
kiln, which is large in diameter. In the kiln, the
powder is heated to 1500 degrees Celsius.
This creates a new product, called clinked,
Clinker is discharged red-hot from the lower
end of the kiln and generally is brought down
to handling temperature in Grate coolers.
The heated air from the coolers is returned to
the kilns, a process that saves fuel and
increases burning efficiency.
3. Cement milling, Storage & Packing:
Portland cement, the basic ingredient of
concrete, is a closely controlled chemical
combination of
c a l c i u m ,
s i l i c o n ,
aluminum, iron
a n d s m a l l
amo u n t s o f
o t h e r
ingredients to
which gypsum
is added in the
final grinding process to regulate the setting
time of the concrete
