offers Rotary kiln Cement plants
that speak innovation, quality conscious and
cost effective technology. We offer Medium
size to Large Size ROTARY KILN Cement
plants from 300 TPD to 2000 TPD on
turn key basis and have capabilities to undertake
all aspects of project including, feasibility
studies, technical advice, equipment supply,
erectioning, supervisory services, commissioning
etc. So that the dust does not escape into
the environment highly efficient measures
for pollution control have been incorporated
in every cement plant. Every
material transfer points is installed with
Reverse pulse jet filters. Electro static
precipitator (ESP) treats the Fuel gases from
kiln for cleaning before discharging into
the atmosphere helping to maintain the eco
friendly environment. |

- 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 first crushing reduces the rock
to a maximum size of about 15 cm (6 po).
The rock then goes to secondary crushers
or hammer mills for reduction to about
7.5 cm or smaller.
- Raw milling & Blending:
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, a
closed circuit ball mill equipped with
high efficiency separator. After achieving
the 90 microns size the fine grinded material
also known as raw meal is sent to the
continuous blending silos (CFC) for homogenization
& extracted by means of load cell
hopper for the next step which is feeding
to the kiln pre heaters.
- Pyro processing:
The raw material is heated to exceeding
1,450 °C (2,700 degrees F) in huge
cylindrical steel rotary kilns
lined with special firebrick. Kilns are
frequently as much as 3.7 M (12 pi) in
diameter, large enough to accommodate
an automobile and longer in many instances
than the height of a 40-story building.
Kilns are mounted with the axis inclined
slightly from the horizontal. The finely
ground raw material or the slurry is fed
into the higher end. At the lower end
is a roaring blast of flame, produced
by precisely controlled burning of powdered
coal, oil or gas under forced draft.
- Burning and cooling:
As the material moves through the kiln,
certain elements are driven off in the
form of gases. The remaining elements
unite to form a new substance with new
physical and chemical characteristics.
The new substance, called clinker, is
formed in pieces about the size of marbles.
Clinker is discharged red-hot from the
lower end of the kiln and generally is
brought down to handling temperature in
various types of coolers. The heated air
from the coolers is returned to the kilns,
a process that saves fuel and increases
burning efficiency.
