The article presents the experimental results of a new composite ring drum that
cleans cotton of small impurities The results of a full-factor experiment of the
recommended composite spiked drum with an elastic element are presented. The
boundaries of the input factors and the levels of their change are given. The planned
central composite experimental matrix was constructed, the calculations were performed
on the basis of the constructed table, and a regression equation was obtained that
determines the cleaning effect. Dependence graphs were obtained for changing the
number of revolutions of the drum, changing the distance between the spikes and the
mesh, as well as changing the surface of the mesh, which affect the cleaning effect. From
the analysis of the graphs, the optimal values of the composite spiked drum are shown

The article provides an analysis of the state of technical equipment for cleaning fibrous materials, including raw cotton from fine and coarse litter. The scheme of the drive of the cotton-cleaning unit including belt drives with eccentric tension rollers with elastic elements is presented. The results of experimental studies of a belt drive with variable gear ratio, including a composite eccentric tension roller, used in the drive of a cotton-cleaning unit of installation cotton ginning complex (ICGC), are analyzed. On the basis of full-factor experimental studies, the optimal values of the drive parameters have been determined, which allow obtaining a high cleaning effect.
