Ginning and Pressing Process -

The following technologies are being used for cotton ginning in the world:
1. Saw Ginning
2. Roller Ginning
(a) Double Roller Ginning
(b) Single Roller Ginning
(c) Rotobar Rotary Knife Roller Ginning

From the field, seed cotton moves to nearby gins for
separation of lint and seed. The cotton first goes
through dryers to reduce moisture content and then
through cleaning equipment to remove foreign matter.
These operations facilitate processing and improve fiber quality.
The cotton is then air conveyed to gin stands
where revolving circular
saws pull the lint
through closely spaced
ribs that prevent the
seed from passing through. The lint is removed from
the saw teeth by air blasts or rotating brushes, and
then compressed into bales weighing approximately
500 pounds. Cotton is then moved to a warehouse for
storage until it is shipped to a textile mill for use.
A typical gin will process about 12 bales per hour,
while some of today’s more modern gins may process
as many as 60 bales an hour.
