The article presents the results of research on the improvement of the grate to improve the efficiency of cleaning cotton gins from major contaminants. To achieve the goals of increasing efficiency, the existing technologies for cleaning raw cotton and the equipment used were analyzed. In the studies, industrial varieties of raw cotton, the most common in the region, were chosen as raw materials. Cotton I-technical grade was used with a soiling level of 6.6% and a moisture content of 8.2%. By attaching the cotton wool to the saw drum, one can increase the distance between the posts by increasing the distance between the strings by moving the first post down a distance L to make sure it also goes to the lower drum of the saw in the access path. In the experiments, the distance between the first column and the second column was set equal to 40 mm, 50 mm, 60 mm and 70 mm, and the distribution of sawdust in the drums was studied taking into account the amount of cotton transported. The main attention during the experimental studies was directed to the location of the grates relative to the saw cylinder and the distance between the grates. For experimental studies, laboratory equipment was manufactured and carried out in the conditions of the Joint-Stock Company “Scientific Center of the Cotton Industry”. As a result, with the improvement of the location of the grate on the grate, the cleaning efficiency was 42.6%, and the number of pieces of cotton in the waste was 5.2%, as indicated in the technological description of the unit, the number of grates increased by one unit.
