Currently, SX and SS-15A types of separators are used in production. Separators are used
to separate the seeded cotton from the air stream coming through the pneumatic conveying device.
Also, the separator cleans the cotton from dust and some small impurities as it transfers the dust
and small impurities in the cotton together with the air.

Introduction
At present, one of the main types of transportation of seeded cotton from warehouses to
production and interdepartmental transportation in cotton ginning enterprises is the method of
pneumatic transportation. The pneumatic conveying system is easy to use and maintain, reliable,
and does not lose raw materials during transportation. Cotton separators used in the pneumatic
transport system are very important. Separators are the only equipment that affects the normal
operation of the pneumatic transport system, its performance and aerodynamic mode of operation.
In the working chamber of the new separator offered to cotton gins, mesh surfaces in
the horizontal plane are placed in a different order compared to the mesh surfaces of the existing
separator. As a result, cotton will reduce contact with the mesh surface of the separator as it
separates from the air in the separator working chamber. This, in turn, preserves the natural
properties of fiber and seed, and prevents free fibers from leaving dust with air and clogging in
the separator.

ginning enterprises. The pneumatic transportation system is easy to use and repair, and there
is no loss of raw materials during transportation.
Cotton separators used in the pneumatic transport system are very important. Separators
are the only equipment that affects the normal operation of the pneumatic transport system, its
performance and aerodynamic mode of operation.
Currently, SX and SS-15A types of separators are used in production. Separators are
used to separate the seeded cotton from the air stream coming through the pneumatic conveying
device. Also, the separator cleans the cotton from dust and some small impurities as it transfers
the dust and small impurities in the cotton together with the air.
SS-15A - model cotton separator - The separator is made entirely of iron, it is reliable
during operation, it works with high efficiency. The seed cotton mixed with air falls at a high speed
through the pipe into the separation chamber (2) of the separator. The cotton moves by its own
inertia through the wall of the separation chamber and rests on the rotating blades of the vacuum
valve (7), and due to the rotation of the blades, the cotton is thrown out of the separator. If there is
air, it loses its initial speed inside the chamber, then changes its direction and is directed to the
dust collection devices through the air transfer pipe (6) due to the suction of the fan from the holes
of the grid (4) on both sides of the chamber.

Conclusion
Increasing the number of rotations of the drum of the separator with a cylindrical mesh,
which is offered to cotton cleaning enterprises, makes it easier to separate cotton from the surface
of the mesh by increasing the rotation speed of the drum, and the cleaning efficiency of the
separator decreases. As a result, we can achieve quality fiber.
