“…Figure 4 show plots of the distribution of the flow rate of the mass of seeds along the contour for various values of the angle and parameter, indicating its mechanical properties.It can be seen from the graph that the flow velocity along the circuit is close to a linear regularity, and with increasing parameter A, the flow velocity decreases upon exiting the circuit. It is also seen that with increasing angle 4 β practically does not affect the distribution of speed.The parameter can significantly affect the change in flux density (Figure4) and with its increase, an increase in density, the formation of the mass of compacted seeds on the grate circuit is possible[12] [22][23].…”

Improving the efficiency of the process of separating fiber from cotton seeds by improving the working chamber of the gin is one of the important issues. The main way to increase the efficiency of sawn gin is to increase the fiber content in the mass of seeds in the working chamber with a uniform decrease in its density. This can be achieved by using grates with a concave working surface, which serves to move the seeds away from the rotating saws and accelerate the release of bare seeds from the working chamber. The article discusses the movement of seeds on the concave surface of the grate and determines the rational parameters of their working part. The article explores the proposed grate model, consisting of four geometric shapes, provides an analytical analysis of the geometric types. The dependence of the location of the last rectilinear part of the general contour on the shape of its convexity and concavity is determined. Cotton seeds move along the contour in the form of a stream. We assume that the thickness of the flow along the contour is constant and equal. We compose a unique equation of the flow in each section of the circuit. To determine the state of the flow, we denote its velocity, density and pressure in each section, respectively. Let us determine the flow motion along the contour with respect to the arc.

The study results on the 6A-12M1 apparatus with upgraded screw conveyor piles are presented in this paper. Studies were conducted on the small-impurity removal apparatus used in the Rishton cotton ginning business. A better version of the spiked cylinder augerwas incorporated into the initial part of the second of the two side-by-side cleaning machines, 6A-12M1, throughout the technical process. Comparisons can be done between portions or the entire apparatus. The research's findings indicate that the 6A-12M1 equipment in the current version has a cleaning efficiency from minor contaminants that is 28.3% lower than that of the new equipment. Additionally, the cotton fibers were grown under production conditions in order to ascertain the impact of the 6A-12M1 small dirt cleaning equipment on the fluffing of the cotton fibers and the impact on the change in the amount of fluffed cotton pieces when these cotton fibers are processed in the UXK small and large dirt cleaning equipment. The research that was done is provided with the results it found. The results of the research indicate that while 28.22% of cotton fibers were blown in the 6A-12M1 cleaner, the amount of blown cotton particles decreased to 11.46% after large impurities were cleaned in the two saw drums and rib modules in the UXK cleaning complex. Meanwhile, 88.54% of the cotton was unspun. Therefore, it was discovered that while cleaning big pollutants in the UXK cleaning complex, the number of cotton particles may be reduced by up to 2.5 times with the presence of two sawing drums and a screen grid module.

In recent years, there have been many researches devoted to the theoretical foundations of the sawing process. However, among them, there are none devoted to the study of the process of extracting the fiber separated from the seed from the saw teeth. From this point of view and based on the existing problems of fiber removal in saw teeth, this research aims to fill this gap and analyze the problems related to this topic.
