A grate with an improved design was developed to effectively clean fibers produced from high- and low-ginning cotton varieties during ginning, thereby enhancing fiber quality. The manufactured grate was installed on a 5DP-130 gin at the Uychi Cotton Cleaning Plant of “Uchkurgan Textile” LLC, improving the gin, and comparative tests were conducted with a 5DP-130 gin equipped with the existing grate design using Namangan-77 cotton varieties I and III.
In the tests, in the 5DP-130 gin equipped with the proposed grate, the mass fraction of defective fibers and impurities in fibers cleaned during ginning of I and III varieties averaged 3.14% and 3.95%, respectively, which was reduced by 0.13% (abs.) and 0.24% (abs.) compared to the fibers cleaned by the gin with the existing grate. During fiber cleaning, the fiber content in the waste decreased on average from 2.3% to 2.7% (abs.), and the cleaning efficiency increased by an average of 3.7% (abs.) and 4.2% (abs.) compared to the existing gin.
After ginning, when fibers were further cleaned using a 1VPU fiber cleaner, the mass fraction of defective fibers and impurities in the cleaned fibers averaged 2.0% and 2.96%, respectively, which showed an improvement of 0.14% (abs.) and 0.18% (abs.) in quality compared to fibers produced using a 1VPU cleaner after the gin with the existing grate. According to the O’zDst 632:2010 state standard, varieties I and III corresponded to the “Excellent” class.
The results of the study showed that improving the 5DP-130 gin with a new grate design leads to enhanced fiber quality during ginning, a reduction in waste fiber content, and an overall increase in cleaning efficiency of the roller gin.
