Abstract
Cotton in the article has high humidity and pollution The technique and
technology of initial processing of dirty, especially machine-picked cotton, processes
of separation of impurities from the moving particle composition are considered.
Keywords:
cotton, cotton wool, model, pollution, fibrous waste.
Introduction.
Globally, it is more important to improve the pre-treatment
techniques and technology of cotton with high humidity and pollution, especially
machine-picked cotton, to develop the theoretical basis of the processes of cleaning
cotton from small and large impurities, to justify the movement parameters and
working modes of working parts and mechanisms, through which cotton can be cleaned
and cleaned. extensive theoretical and complex experimental studies are being
conducted to determine the optimal values of geometric and kinematic dimensions that
provide At the same time, ensuring the effectiveness of cotton cleaning and maintaining
the initial quality indicators of the product, including creating mathematical models
that allow choosing the optimal modes of cotton cleaning that do not negatively affect
the quality of the product, and reducing the strong shock effects when cleaning cotton
from dirt and impurities, developing soft mode technologies of cotton cleaning. output,
creating constructions of resource-efficient working bodies of cleaners is becoming
important.
In our republic, comprehensive measures are being implemented to improve the
techniques and technologies of cotton industry enterprises and technical re-equipment,
to increase the profitability of cotton raw material processing and the competitiveness
of manufactured products. In 2017-2021, the Strategy of Actions for the further
development of the Republic of Uzbekistan, including the task of increasing the
competitiveness of the national economy, reducing the consumption of energy and
resources in the economy, and widely introducing energy-saving technologies into
production, is defined. In the implementation of these tasks, including the improvement
of the technology of initial processing of cotton, in particular, the development of an
effective technology for separating impurities from its content by cleaning it before
storage, and the development of a rational arrangement of working bodies that ensures
high cleaning efficiency, soft impact regimes based on the determination of the
trajectories of the working bodies and cotton components in cotton cleaning.

From the analysis of the given graphs, when the inclination coefficient increases,
it is observed that the distribution laws of density and cleaning efficiency change
according to ey. In its small cuts, the density decreases during the interval, and the
efficiency reaches a maximum. These laws make it possible to choose the coefficient
of inclination of the raw material medium in which it is transferred to separate the raw
material from impurities.[7]
