Krishna Sai Granites (KSG) Group of Andhra Pradesh,
began quarrying Black Galaxy granite in 1992. Today, it has become a large
producer of the material, with six quarries in the village of Chimakurthy.
Nearly 20 years ago, Krishna Sai Granites (KSG) Group
was founded by Venkateswara Rao Sidda, who worked diligently to develop
numerous quarries - particularly several for Black Galaxy granite. Today, the
company, which is based in Andhra Pradesh, South India, has grown to include
more than 10 quarries, a state-of-the-art fabrication facility and 1,400
“The firm was started in a small traditional family business profile, and
gradually expanded its wings in quarrying, processing and making steps towards
the execution of projects globally,” explained Bharat Sidda, Executive Director
of KSG Group. “Today, KSG Group is known as the number one producer, processor
and exporter of Black Galaxy granite.”
After starting KSG Group in 1992, Venkateswara Rao Sidda received extended
support from Hanumantha Rao Sidda, who is a fellow member of the Institute of
Chartered Accountants of India and has vast experience in the granite industry.
“He has rich and varied experience in the areas of capital market, finance and
general management,” said Sidda. “He is well exposed to and familiar with
international business. He believed raw material was the strength of the
industry. After consolidating the quarrying activities, KSG went forward into
processing slabs under my close surveillance. I support the various key
functions related to innovations, communication and client relationship.”
In the quarries, the company utilizes an array of
equipment, including 30 excavators from Hitachi, L&T and Caterpillar; five
110 Commando drillers, three 120 Commando drillers and two Rangers - all from
Tamrock (Sandvik Mining); 25 Chicago Pneumatic compressors and 10 Atlas Capco
compressors; 25 dump trucks; four derricks; 10 cranes; and 28 trailers for
Currently, KSG Group owns about six Black Galaxy quarries that are located in
the village of Chimakurthy, which is approximately 11 miles from Ongole - a
small town that sits at Chennai National Highway No. 5. The closest airport is Vijayawada, which is
about 105 miles away. Among the additional granite quarries owned and operated
by KSG Group are: Black Pearl in Gurijepalli (V/M), Steel Grey in Ballikurava
(V/M), S.K. Blue in Dontha (V/M) Srikakulam, Miracle White in Sithampeta (V)
Srikakulam and Tan Brown in Karimnagar, which will be operational in a month or
two with 400 to 500 cubic meters per month.
“Being one of the early promoters of Galaxy, and now being the biggest source
with unparalleled excavation of granite in the region, KSG prioritized in
sticking to high-end and latest technologies available, and always ensured to
match the client requirements by catering to the best-quality blocks,” said
Sidda. In the quarries, the company utilizes an array of equipment, including

In total, KSG produces approximately 45,000 cubic
meters of rough material annually. The company maintains two processing plants
only 4 miles away from its Black Galaxy sites where the blocks are cut into
slabs and finished products.

“After achieving its peak in quarrying, which was the primary focus, KSG
started to widen its vision, and it started to focus on reaching the
international markets to provide cut-to-size [products] and small slabs,” said
To execute this idea, ‘Unit 1’ was established in 2004 with 12 block cutters in
place to process smaller blocks. “This Unit was the first of its kind in the
Ongole region - with a production capacity of 120,00 square meters (1.3 million
square feet) of smaller slabs annually,” said Sidda. “It paved footsteps to
cater to the overseas requirements of the Middle East, Europe and partially to

The increased requirements in the world market, and
the necessity to deliver quality slabs, led KSG to establish “Unit 2” - with
state-of-the-art machinery from Breton, Gaspari Menotti, Simec and GMM - in
2009. “The strategic geographical location of our plant enhances proximity and
direct access to our quarries,” said Sidda. “The port is just 270 kilometers
[168 miles] away.”
For slab production, the process begins by trimming the blocks with two
Bideseimpianti wire saws from Italy.
“They trim the blocks so as to obtain the perfect size slabs,” said Sidda.
“Only high-quality diamond wire is used in order to get regular trimming. All
the block trimmings are carefully inspected by KSG’s highly experienced
After trimming, the blocks are processed in a specialized plant housing four
Gaspari Menotti Jumbo 480 series gangsaws. “They are the best slab-cutting
machines in the world,” said Sidda. “They are capable of cutting slabs in
thicknesses of 20, 30 and 40 mm.” With four gangsaws, KSG has the capacity to produce
a total of 300,000 square meters (3.2 million square feet) of granite slabs
annually, the company reports.
Blocks are processed into raw slabs on four Gaspari
Menotti Jumbo 480 series gangsaws.
Once the blocks are processed into raw slabs, they
move to the slab-production line, where a fully automated and computerized
22-head KG-3000 Ultrex polishing machine from Breton S.p.A. of Italy plays an
important role in the production process. “Before polishing the sides, the
edges are trimmed for perfect finishing,” explained Sidda, who added that
tooling is supplied by Nicolai Diamant and Abrasivi Metallici. He added that
the use of this tooling has provided the company with “outstanding results” in
the final product.
For resin-treated material, KSG operates a fully automatic resin line from
Simec S.p.A. of Italy, which has two large-scale driers and holds a combined 40
slabs at one time. The company uses epoxies from Tenax of Italy on the slabs.
During the process, the slabs are first preheated in one of the drying units,
then the resin is applied, and a second drier allows for optimal curing of the
A GMM Eura automatic bridge sawing machine is also in place at the plant for
cut-to-size work and other applications. “This machine enables KSG to make
accurate cuts in the slabs as per the specification,” said Sidda.
“The growth percentage of the sales in the U.S., Europe and Middle East brought
us to the extent of establishing one more processing plant, “Unit 3,” which
will be operational in the coming year,” Sidda went on to say. “It will not
only cater to the requirements for slabs, but also tiles, project execution and
even cut-to-size requirements.”
A fully automatic resining line from Simec S.p.A. of Italy, which
holds up to 40 slabs at one time, is used in the production process. KSG uses
epoxies from Tenax of Italy on the slabs.
According to Sidda, KSG places a special emphasis on quality packing and
effective shipping. “Crates and pallets are made of expensive and quality
wood,” he said. “Wood packing materials (WPM) are as per USDA & ISO
standards. The WPM is marked with an IPPC logo and ISO country code. This
authorizes and authenticates the fumigation proceeds to International Standards.”
A fully automated and computerized 22-head KG-3000
Ultrex polishing machine from Breton S.p.A. of Italy also plays an important
role in the production process. “Before polishing the sides, the edges are
trimmed for perfect finishing,” explained Bharat Sidda, Executive Director of
KSG Group, who added that tooling is supplied by Nicolai Diamant and Abrasivi
KSG also reports that it is equipped to load four
containers at any single point in time. “We can load both closed-top and
open-top 20-foot containers,” said Sidda. “Packaging experts with the latest
‘C’ clamps with mechanized nailing guns make the packaging division stand out.
Slabs are inter-packed with plastic and soft foam sheets so as to reach the
customers in perfect condition. We have a record of loading eight crates in a
container, and apart from pallets and crates, KSG also does A-frame loading.
In 2009, a total of 11.43% of KSG’s granite products was exported to the U.S.,
and the company’s presence in the market was bolstered by its investment in
state-of-the-art production machinery. “This enhanced how to focus on the U.S. market,
especially,” said Sidda.
A GMM Eura automatic bridge sawing machine is also in
place at the plant. “This machine enables KSG to make accurate cuts in the
