Annotation.
Preparation of cotton raw material for processing means keeping
it free of defects and damage before production. Modern drying drums have unique
universality in the processing of cotton raw materials, and are designed for storage
and transfer of cotton raw materials to the technological process.
Key word.
Saw drum, colosnik grill, air nozzle, dirt removal auger, brush.
At the present time, cotton ginning enterprises use modern technology, i.e.
2SB-10, SBO, SBT brand drying drums are installed in the drying and cleaning
department to achieve high levels of drying efficiency. In the direct cleaning
department, there are also modern cleaning machines, such as UXK cleaning flow-
line unit, Mekhnat cleaning machine and other equipment.
The task of the dryers is to prepare cotton raw materials for storage at the
preparation points, to achieve the conditions intended for one-time drying, that is, it
should have a high productivity in terms of moisture. Secondary drying has a bad
effect on externalization, which has a negative effect on production and costs. The
function of the indicators is to transfer cotton raw materials to processing - to achieve
productivity of cotton raw materials, to ensure even and smooth drying of fiber and
seed, to give fiber properties, to increase their resistance to mechanical impact.

in the technological process, increasing the F.I.K of the equipment. For this purpose,
an automatic bunker feeder is installed so that the equipment in the technological
process works smoothly.
Its circuit structure is shown in Figure 3 (a and b)..

Figure 4 (a, b). Scheme of the automatic hopper feeder.
The automatic bunker feeder mainly consists of two parts found: from the
lower and upper parts:
The bottom part is the main part, 6 plate transfer drum diameter 270 mm
adjustment from 1.14 to 11 rpm, the pile carrier drum is installed under the transfer
drum, the performance is automatically adjusted by changing the number of
revolutions of the transfer drums .

Wet cotton raw material goes through a separator into an automatic control
hopper, from where the work given from here passes through a productivity
screening device and goes into an injection funnel. The flow of the drying
agent, coming from the heat generator, moves from the funnel with raw cotton
to the dryer and passes through its chamber and enters the air chamber of the
separator-cleaner due to the suction created by the fan. The drying agent
separated from the cotton raw material is released into the atmosphere, and the
cotton is cleaned of small impurities and enters the injection funnel from here,
and then the cotton raw material is transported to the second drying equipment.
Conclusion:
Ensuring the smooth operation of the equipment in the
technological process of the initial processing of cotton and the control of the
technological process. At the same time, it is considered one of the main reasons for
resource-saving equipment in the technological process, increasing the F.I.K of the
equipment.
