The article presents the general scheme and principle of operation of the modernized design of the raw cotton cleaning unit, presents the results of full-factorial experiments of the cotton cleaner with different diameters of drum peg and multifaceted grates, substantiates their main parameters. The results of production testing of a prototype cotton-cleaning unit in production conditions are given. In the drum zone, pegs of different diameters are used in the fine waste removal zone, as well as compared to the existing technology in the large waste recycling zone. The optimal values of the diameter of the pegs and the number of grates of the grates are determined on the basis of experimental studies, recommendations for use in production are given.
