Introduction:
Ginning is the first mechanical process involved in processing cotton. Ginning
mill separates cotton fibers from the seed bolls and dust particles. The main
application of ginned cotton referred to as lint is for spinning operations, where
lint is converted to yarn.
Market:
World production of cotton stood at 137.8 million bales in the year 2008-09. The
leading producers include China, India, USA, Pakistan, Brazil, and Turkey.
Cotton textile commands a significant share in exports from India. It accounts
for nearly 22% of the total exports. Area, production and productivity of cotton
in India in the year 2008-09 stood at 93.73 lakh hectares, 290 lakh bales(170 Kg of
each bale) , 526 Kgs per hectare.
A.P. stands 3rd rank in Cotton area in India with 10.96 lakh hectares (Ha) next
only Maharashtra (31.91 L.ha) and Gujarat (25.96 L.ha). The share in area of A.P.
in India is 11.5 %. It also stands 3rd in cotton production in India with 43.00 Lakh
bales (Bale is 170 kg each) with an average yield of 667 Kgs next only to
Maharashtra (60.00 L.B) and Gujarat (110.00 L.B). Adilabad, Guntur and
Warangal had recorded higher growth in cotton area cultivation and production.
Pressing:
Cleaned Lint is taken to the bale press which compresses the ginned lint into
bales that weigh around 170 Kgs. After pressing is completed the bale is
tightened and covered fully with cloth, after then the bale is weighed and kept in
the hall safely.
Packaging the Lint:
The bales are then wrapped with a protective cover, ready for delivery to the
warehouse where they are sold to various textile mills
. Technology:
The technology required for the ginning & pressing operations are cotton
ginning machinery, pre cleaner, lint cleaner, Kappas conveyor system, lint
conveyor system, Hydraulic cotton baling press, conveyor for seed, electrical
infrastructure, Humidifier and weigh bridge etc. The other optional machinery
required is the foreign fibre detectors/removers.
